You will need to replace the resistor module.You also need to check the connector real closely cause they get hot and melt the plastic.If you just replace the resistor you will have the same problem in a few months.So make sure and check it over good.Hope this helps.Good luck.

The blower motor resistor is located either under the passenger side of the dash or behind the glove box. It will be near the blower motor. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

very easy first you go buy one then look under the glove box near the blower motor you will find it usually two or three screws holding it, and a large plug connects to it. very simple to do.because you have it in hand it makes it easier to compare to what you see under there.good luck

T he blower motor only works in the hi position , i believe i need a new resistor, where exactly is it located ? on the blower motor itself and inside the vehicle? do i need to tahe the blower motor out?


I have a 2000 jeep grand cherokee and recently had the same problem...only I actually replaced my blower motor before I found that it wasnt the issue. The blower motor resistor is located on the passenger side under/behind the glove box. It will have 2 screws in it and a wiring harness coming out of it. Very easy to replace. Cost is about 115-145 depending on where you buy.

2006 grand cherokee laredo heater fan only works on high, I had the same problem with my sebring sedan and had to replace heater fan motor. Is this likely the same problem? Where is it located?


It is NOT the motor itself in this case, it is the blower motor's resistor pack, which was and seems still is a common problem with the grand cherokees. It is usually located under or behind the glove box right on the firewall, and some rarer cases under the hood, also on the firewall but on the hood side and not the inside of the vehicule, next to the blower motor assembly. In your case it should be located inside the vehicule and requires removal of the glove box according to a few tech experts on the web. Here is the section of tech info i have found which i think will be the most useful for you:

"Get to the blower motor in a Grand Cherokeemag-glass_10x10.gif by first disabling the airbags. Unscrew the glove box and remove it. Unscrew and remove the blower motor wire harness found directly behind the blower motor. Unscrew three screws holding the blower motor into place and then remove the motor."

So I hope this helps you out.

2005 Jeep Grand Cherokee laredo air only works on high


The blower motor resistor is bad. The reisistor is located under the dash by the blower motor. If the car has auto temp, the resistor is like a small module and can be expensive.

2001 Grand Cherokee Limited a/c Blower Motor not working


Try wiggling the connector on your Blower Motor Resistor. They are known for having a bad connection and melting the connector. Check on Ebay, I bought a new harness kit on there. It was easy to install, just cut off the old connector and splice in the new. The colors match so there is no guessing which wire goes where. Only cost me $12 and saved me $300+ that the dealer wanted.

Under the glove box beneath the dash the resistor should be screwed into the heater housing.
