I've been dealing with a small cooling fan problem and have been getting help at jeep forum, but i thought i would throw this up here to see if anyone here has ideas....
The facts...
98 Cherokee 4.0 with a/c
Problem: overheating randomly in heavy traffic in hot weather, pretty sure its only with a/c engaged
What i can test:
-fan is working when current is applied from battery to it and will run with no problems...ran 10 minutes
-ac works and blows cold air, but compressor engages and disengages at its own leisure fan does the same in conjunction with the a/c clutch on and off
-temp gauge works
-when temp reaches 210 aux fan shuts off completley and will not come on with a/c or at all...(this is when it is supposed to be continous)...however it took me a while to get to this point so this has only been tested once. this would explain though that the temp will take a long time to get to 210, but takes very little time to over heat once this temp is exceeded
is this a phantom problem, or does a real solution exist short of installing a manual override. i have no problems wiring, as a theatre electrician, however if anyone has a schematic or easy tips it would be appreciated.
