How to repair Jeep Grand Cherokee Heater Blower Resistor.


I own a 2005 Jeep Grand Cherokee. I haven't had any major problems with my Jeep until the heat started fading. First the low speeds went out and then medium...until I was left with high. This might not seem too annoying, but trust me. It's not very comfortable driving an hour with blasting heat!

What's the fix? The blower motor was working fine because it still pushed out the heat on high. This leaves you with the blower resistor. In this blog, I will show you pictures I took on my cell phone step by step how to change this blower resistor out on your own Jeep.

NOTE: You DO NOT NEED TO REMOVE ALL OF YOUR PLASTICS!!! I removed mine only to see where exactly under the passenger feet area the blower motor was. Only after I removed all of the plastics did I realize it was not necessary. The blower motor is 100% covered up with plastics, but if you simply remove the glove box door, you will have instant easy access to the resistor and the screws to dismount.

What you will need:
-Straight slot screw driver
-Star Tip or Allen Wrench
-Flash Light
-New resistor (Part #5143127AA)
All dealerships charge different prices. I paid $9.50. It should be about the same price.
-Patience and about 15-20 minutes to perform the job.

If you would like to make any of these pictures larger, just click the picture and you will be able to see much more detail.

Step 1. Slide this small plastic hinge by sliding towards you and pulling out toward the door.



Step 2. Remove the left side of the glove box by separating the hinge from the metal bar.



Step 3. Remove the right side of the glove box.



This is what your dash board opening will look like without the glove box.



Step 4. Remove the two screws that hold the resistor in place. You will need a star tip screw driver. I did not have one, so I used an HEX tip. Be careful though, doing it with a HEX tip could strip the screw if you are not careful.



Here is a picture of the HEX tip I used. (Also known as an allen wrench.)



Remove the two screws and it will come out like this.





You can see the red resistor where it burnt out. Some viewers have commented that their wire harness was melted. There are four wires, one for each speed. Make sure you replace the harness too (if it has melted). Not only will your speeds work again, but you reduce the risk of electrical fire from a short in the wire.



Step 5. Place the new resistor back into the mounting hole and tighten down the two screws.





Note: At this point, you should turn your key into the ON position. Make sure the radio is off so you have pure silence. Start your blower speeds from Off, 1 (low), 2, 3, 4 (high). Make sure they all work. If your heat speeds still does not work. You most likely have a more serious problem on your hands.

Step 6. Hook the hinge back on the glove box. Then clip the two mounting hinges back into place. I used the removal picture. It is still the same idea, just putting it back on this time.




Now you have successfully changed your heat blower resistor! Congratulations! Be sure to check out the comments section below in the link provided. Many viewers have had the same or additional trouble shooting issues which have been resolved through community support. Thanks for visiting!

Thanks so much for the detailed istructions. I have been struggling with this for about a year and now it works great!! Took me about 20 minutes to fix. I appreciate you taking the time to help others with the same problem!! :))

Tyler said...

A big help! Thank you! The garage quoted me $163 to do the job, I bought the part for $20 and fixed it myself in less than 20 minutes!

hey man great job,did it in 20 minutes and 15 of those was trying to find latch to release the actual resistor...lol,thx again

Matt in Atlanta said...

The dealership diagnosed the problem for me, but wanted $230 to replace blower motor resistor. I got the part for $10.65 at O'Reilly's and with your help had everything working again in 10 minutes. Thank You!!!!!

You rock! Took about 10 minutes and now it works like a charm. I got my part from 123autoparts.com and it was $23 with shipping. I am amazed it was that easy. Thank you!!!

Greg Bailey said...

So in my 1999 grand Cherokee Limited its not blowing anything, hot or cold. When i go down the road it will blow a little bit but how do i findout if its the motor or resister?? Also is there a way to test the blower motor?

Eugene Coons said...

Mine does not look like that but it the same procedures. Thanks for the tip

I too helped a neighbor with his 2000 Grand Cherokee. The original was melted and fried at the connector from under dash wiring to the Resistor. First he tried a used resistor and plug pigtail from a junkyard. After 1 mo or so it did it again and again the connector was melted to the resistor. Got an UPDATED Jeep resistor with larger contacts and the updated wiring pigtail. Installed it all and blower appears to be operating slower. From comments it appears the new pigtail is wired backwards with the +Pos and -Neg reversed. Effectively running the blower backwards. Have to do some more checking to verify. I don't want to fry anything just swapping the wires.

Ok it's confirmed on a 2000 Grand Cherokee LTD with the auto climate, the new JEEP UPDATED resistor located under the dash on Pass side, is sold faulty. The jumper from the resistor to the blower motor is wired backwards. The new Green + should be the Black – and the Black should be the Green+. The wires need to be cut and swapped to operate correctly. As sold the new resistor will run your blower backwards and be barely audible. You can compare the old blower connector to the new jumper and see it's the opposite. At least a year later they are still being sold faulty. Send a letter and a bill to the dealer and make them pay for the repair of a faulty product.

Thank you so much for this. Yesterday, my wife reported a burning rubber smell, which quickly dissipated. I suspected it was related to the HVAC system since it has been getting louder and louder. It's probably the burnt harness. Thanks again!

Thanks for the write-up, worked perfectly and took about 5 minutes. Much nicer now that I dont have to drive with high heat only!

Anonymous said...

I think this thread has the exact information I need the amount of air coming through is good on high but high is the only heat setting I have .it would work on the other setting if I slammed the glove box really hard lol but that stopped working thanks for the info

Here it is June 28,2013 and your article is still helping people. I went straight to the resistor and the connection was loose. Didn't even need a tool to lower glove box door. 5 minutes fix. Thanks for the post. Randy

Rob said...

mine looks a little different with a sealed ceramic reistor, so is there a way to solider a reistor across the low to high side to get it working, Napa wanted $131 to replace the part, I can live without low speed fan for that much money

Hi, thanks for your post! I see you wrote it some time ago, but I'm hoping you are still up for giving some advice. I have 2001 GC. All summer my blower had been going on and off. I'd give the glove box a little shake & it'd turn back on for a few days then off again. A couple of weeks ago, the fan started to sound very loud. Today, the fan no longer kicks on. When I turn the heat or AC on, I can hear the thermostat click on, but no blower. Any ideas? Is this something that a mechanic shill charge an arm & a leg for? There's no way I can justify putting another 1000 into the car for the AC again (compressor was replaced.). Does the entire dash need to be pull out to replace the blower? Thanks!!!

bvensko said...

@ Previous post, It really sounds like the blower motor just died on you. I did a little search and you can find a new blower for about $60 shipped. Unfortunately, I haven't worked on a 2001, however I would imagine they keep the location of the blower in the same position as the 2005+. You shouldn't need to remove any parts of your dash. Take a look at this picture

It will give you an idea for what you need to do. Best of luck!

Rob B said...

Thank you so much for the information. I replaced the resistor, but the connector going to the old one showed signs of being burned and charred, so the connector or part of the harness will need to be replaced. I didn't get the blower working, but I did replace something that probably needed to be replaced, and I know what to tell them at the repair shop.

Anonymous said...

I love the internet. Same thing happened on my old '95 sport, so I knew when the fan went what the issue was. However, your pictures made it a snap to replace. I wouldn't have thought about removing the glove box until I had ripped out all the dashboard.

Troy Thibodeaux said...

Thanks for your tut. Very informative. I'm having trouble getting connector off. I know it probably just pulls right out, but I can't get without breaking everything. I think I need to replace the connector and harness anyway, as I have a melted wire where it goes in to the connector.

Scott Perratti said...

This is why the internet is SO great.. It allows other people to help fix a problem which can be as easy as pushing in a wire, where a shop would cost big bucks to diagnose..
THANK YOU!!!

Cat said...

Hi, I read your instructions to remove the glove box in order to get at the blower motor resister, but on my 2008 JG Cherokee,there are plastic "fins" in the upper part of the inside hinge which makes it impossible for me to pop it up off of the hinge bar to remove the glove box. Is there any other way to get at the resister?

This took all of 5 minutes to do and saved me 100s! THANK YOU

05 grand cherokee , nothing blows out , hot or cold air

BO said...

Question? How do you know its not your face plate control! On 93 Grand Cherokee its hard to tell if its burnt out because its a rippled metal piece

Justin Bull said...

What if its only blowing out cold air? I have a 2006 Jeep Grande Cherokee Loredo, few days ago it only blew out cold, so i changed the thermostat AND heater core, but it is still blowing out cold air. Lost at what else it can be.

Mia said...

I have a 2006 jeep grand cherokee and my ac works fine on both sides, but my heater only works on the passenger side.... any ideas why this is?

Great help! I just fixed it on my 2005 Grand Cherokee! Took me 15 mins!
The part was $23. The store quoted me $150 to fix it!
Glad I was able to save! Thank you

Hi I completed step one but for the life of me cannot understand the picture in Step #2..I have an 05 GC as well, but maybe you guys have taken these glove boxes out before but I just plain don't get it and am stumped..any help explaining the pic better would really free me up!
Thanks,
-Steve

bvensko said...

Hello Steve and Sloan,

There is a little female pivot point that clicks onto a male bar. As long as your step 1 is complete with the plastic swing arm, you can even pull up as hard as possible on the glove box door. You won't break it. You are just unclicking the hinge point. Hope that helps. -Bob

SteveandSloane Josue said...

Thanks Bob - That was it, just needed quite a bit of forceful persuasion on that left side! Got my resistor out too. Thanks to Bob and all on this site.

Alan Herrera said...

Will this help me. My problem is on a 08 gc. My heat on the driver side works great. The fans blow fine. But there are two temp control knobs. Even if I crank the passenger side to the highest heat it blows cold air. But again driver side is hot. Not sure what to do.

Have a 2009 Grand Cherokee that seems to have this resistor problem--no blower fan on any speed. Got the glove box door off in seconds and can see the resistor but the connector is unlike any I have ever seen. How does that thing come off?

What a fantastic resource! Fixed mine this afternoon following your instructions. It took about 20 minutes.
Very much obliged. I got my resistor from eBay. I got the harness just in case too as they were so cheap. Didn't need the harness though. Mine seemed fine.

Hi
I'm having intermittent fan issues in my 2011 Jeep Grand Cherokee but also only have heat on drivers side.
We are going to fix it, I'm just not sure what parts we will need. Can it be the just the resistor?

The blower stopped working in the middle of the ride in my 2009 GC Laredo. Checked the resistor according to your article. The mounting is different from your write-up...I could not remove it but I measured the resistance between open terminals on the resistor assembly. I got what would be expected for healthy resistor: one reads short between two for the highest speed, and the rest shown 1 and 2 ohm resistance. So, what would be the problem? The blower doesn’t operate at any speed..

To the last post, have you checked your fuse panel to see if you just have a blown fuse?

Yes, could not find any that was blown...

OK, I have a 2000 jeep grand Cherokee.. the fan speeds only work on 1,2 and 3... on 4 the unit shuts off.. my mechanic said that he thinks I need a new climate control unit.. the drivers side vent only blows slightly... the center is OK.. do u think that a control unit would solve this air flow issue? or could it be something else.. he said he checked and everything else was fine... but when I got my jeep it had a stalking issue while driving... $3000 later it was because a aftermarket sensor wasn't working with my Chrysler sensors
. It had to be the same.. so yeah.. I like to get another opinion on this issue before it costs me $10,000.. plz help..

I dont know if this blog is still active.I have a similar issue well kind of.My temperature is stuck on cold or hot whatever i select unless i turn the fan on/off and then the temperature changes according to the temp control red/blue is selected.

Any suggestions would be appreciated...
