Does my 2001 Cherokee have a fan control module behind passenger side headlight ? Does anyone have a drivers side power window / window lock/power mirrow control panel ?

 

1. No
2. All XJs have control switch panels. If you mean does anyonr have one for sale check the For Sale section.

Are you trying to fix a specific problem?

 

Yes can't get electric fan to come on when a/c comes on replaced switch on a/c but still not getting power to fan going to put new relay on it !

 

Fuse is good?

In 2001 the auxiliary fan won't come on until the engine coolant temperature hits 218°F or the A/C refrigerant pressure hits a certain threshold. 1999 was the last year for the fan coming on at the same time as the compressor.

 

Go here and read post #42. It describes the switch functions in the 2000/2001 AC system.

https://www.cherokeeforum.com/f2/gre...e-6558/index3/

The Freon charge (pressure) in your AC system may be low.

You can check the electric fan circuit by removing the connector from the Engine Coolant Temperature sensor on the thermostsat housing and starting the engine. If the fan works, the fuses, relay, fan, PCM, and wiring are good. You will get a CEL because of this but it will go away on its own.

If the fan doesn't work check the 40 amp Rad Fan fuse in the PDC.



If it's okay, check fuse #10 in the Junction Block.



If the fuses are okay, you can jumper the fan connector by back probing the Blue wire with a safety pin and connecting the safety pin to the positive post of the battery post. With the connector attached, the ground to the fan is provided so there's no need to jumper it.





The Rad Fan relay in the PDC cannot be swapped with another relay to see if the relay is bad.

Thank you so much for info but replaced hi pressure switch yesterday which I understand controls fan also,fan never came on but don't think it got to 218degrees either but if fan helps regulate pressure it could still kick off compressor because it kicked off ?

 

Did you read post #42 in that link I provided above?

 

Yes read your link still not sure! Is electric fan suppose to come on when you turn a/c on or just when pressure builds up or temp gets 220 ?

 

When you turn on the AC the fan will turn on when the system pressure gets to 280-320 psi, and turn off when the pressure drops below 270-330 psi.

It will also turn on when the engine coolant temperature reaches 223*F.

 

OK replaced relay a/c come on worked about 20 minutes wide open , unplugged temp sensor to make sure fan worked it did took vehicle up the road to get to operating temp fan has not come on yet for temp or a/c . A/c finally shut off I checked all fuses before I started all good , fan does work already replaced high pressure switch and checked low side pressure it was good but fan never come on after 20 to 25 minutes of air blowing wide open help please !

 

Fan blower works but no cold air?

 

I had an AC issue last summer. Everything checked out good. Did a little research and found that there is a shim in the compressor clutch pulley. Removed pulley, took out the tiny shim, put pulley back on. After that I've had zero issues. There's a video on YouTube to show you how to remove the shim.
