Question about 2005 Jeep Grand Cherokee

1 Answer

I have a 2005 Jeep Cherokee Laredo, my AC has just stopped working. I just changed the blower resistor to fix the problem I had when the ac only worked on one setting. Are there any possible solutions to fix my a/c?

There could be many issues realted to a total failure of the A/C. First of all check if the soleniod clutches on whne the a/c is switched on then youmust check for gas pressure in the visible window or you will have to use a pressure tester to check. Get help to get to a confirmation after your logic analysis. If the gas pressure is good then the pumping of the compressor must be the next problem area. If there is no gas then you willhave to check for leaks in the condenserr coils and the cooling coils, the system must be tested with air , checked for blocks before any gasis filled. this is very important test to verify any leaks, and the concerned part must be replaced . If the comprssor is pumping low it must be taken out and serviced, estimate the cost before you attempt as the job needs prrofessional touch and guarantee. Hope you try this out. Good day

Have a good mechanic to check to see if the door of the a/c and heater and defroster is working properly. I had the same problem and one mechanic said he could fix it for $750. I got it fixed by an honest mechanic for less than $100. Good Luck!!

Hey! Oddly enough, mine started with the same thing this morning. I Googled the heck out of this and I'm more than satisfied that the most likely culprit is the blower resistor. This is EXCELLENT how-to guide (with lots of positive results): http://bvensko.blogspot.com/2008/02/how-to-repair-jeep-grand-cherokee.html

1996 Jeep Grand Cherokee Laredo AC blower wont work on high


I'd check the relay and the resistor ...don't have a location for yours but the resistor is always installed into the heater box so it stays cool. you can usually follow the wiring back to the relay as it's generally nearby. Resistor looks like a piece of circuit board material with several wires connected to it with two screws holding it to the heater box so it sits flush except for the wires. It has several coils inside...any that are broken have failed.

Ac blower won't work. Resistor has been replaced 3 times. I think it is the problem now. Is it easy to replace? Where is it?


Blower motor resistors are found on the pasenger side ducts near the blower motor. It should have three wires going to it.

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.
