Electric cooling fan does not come on at any time,even when a/c is on checked fuse , it;s ok.
Checked fan ,it's ok ..difficult to check fan relay , looks different , not like a normal looking relay .it's square and flat , possible solid state style.
Would like to know how to diagnose this problem
I had the same problem and it was the connector on the right side of the radiator had corrosion and lost contact, had to replace the connector, fixed the problem.

The fan relay is located below the r/h headlight bezel and below the plastic moulding. I am replacing the second one in two years. You have to cut a hole 1.5" from the verticle wall at the back of the headlight cavity 2"X2"centered on what looks like a rain gutter in the plastic moulding to access the relay screws. Save the piece you cut out ...you'll want to silicone seal up the rain gutter after. Hope this helps. D

To test a replay you must ground one pole, (86 I believe) and give power to another (56 I think) they will be next to each other or 1-2 pins apart, if you hear a click when you give it power and ground the relay is good

Its the relay,there are two types of relays in 99 to 04 grand Cherokees, ones that have failed and ones that will!

a/c is working but no blower when turning blower switch. can you tell me what is the problem?
My adult son has a 2000 Jeep Grand Cherokee 4.0L/6cyl w/ 76,000 Miles. Electric fan does not work (AGAIN) already replaced once under recall. Vehice drives fine (even with fan not working) as long as the jeep is moving, doesn't have to be going fast, anything above walking speed seems to be enough to push air through the radiator and keep the TEMP gage needle straight up in the center of the gage where it should be. But, stopping for more than a brief red-light or crawling along in traffic will result in over-heating (which disappears as soon as the vehicle is moving again). This situation seems to suggest that the coolant is circulating properly (therefore not likely to be a thermostat or water pump problem). Haven't noticed a loss of coolant, although this issue has occured in the past with this vehicle. Given that the (dealer repaced) fan is less than 6 mo. old, I think it may be the radiator FAN RELAY, but cannot seem to locate it even with the appropriate HAYNES Repair Manual (incredibly bad illustrations). Can anyone tell me where the Fan Relay is located, so we can just repace it to see if that resolves the probem. Obviously, we are trying to avoid taking the Jeep GC to the Dealer without knowing exactly what needs to be fixed so they can do the usual rip-off extravaganza. JCR rsbcriey@comcast.net
I have the same problem - 3 times in 3 years. I replace in the spring and it works great all summer. Come spring and the fan relay is out again. It is at the dealers right now so I will write back later with results.
