OK, if the fan won't work one may have to have the fans replaced,the relays, and the relay contacts depending on the severity of the problem.

I just spent $724 on repairs to my 1997 Cadillac Deville where the technician replaced the fan motors, the relays, and replaced the relay contacts at the harness due to burnt contacts there.

I was experiencing a passenger side (larger) fan that was working intermittently.

The technician discovered that the fans would work intermittently when the fan relays (3 of them) were shook.

I guess the heat got to them over the years.

Good luck on this repair.

Troubleshooting


OVERHEATING GUIDE:
CAUTION! Safety first. Be extremely careful when looking into or putting your hands or any other body part into your engine compartment. Use safety glasses. Keep all body parts away from open carburetor or air intake -- assume it will backfire. Backfires can produce blindness and/or third degree burns. Keep long hair VERY securely pinned up, remove all jewelry, do not wear loose clothing while working on a car. Heed these warnings even when the car is not running. Remember, modern cars have electric fans that can turn on at any time.Be careful not to short the battery -- battery explosions can throw potentially burning/blinding acid. Don't open the radiator cap of an overheated car. When it's cool enough to open, use a rag to block any spray, and open very slowly. Wear hard shoes capable of shielding impact from a dropped part.Take proper precautions when jacking up a car so the jack doesn't "kick out". A "kicked out" jack can be every bit as destructive as a kick from a large horse. Block the wheels, put on the brakes, seat the jack properly. Never crawl under a jacked up car unless it has been properly blocked up and completely secured. Even then, remember that earthquakes, sudden wind and drunk driver impacts happen. A professional lift is always best.The preceding warnings are by no means an exhaustive list of the risks encountered when working on a car. Always use common sense. You assume full and complete responsibility for the use of the information on this page.This isn't just theory. An old skating buddy lost a finger when his wedding ring was grabbed by a fan belt. I met a guy at MacDonalds who spent 2 weeks in the hospital when an open-carb backfire caused third degree burns over most of his forarm. Skin graft city. Imagine if his face had been by that carb.

Possibilities include blown fuse due to too much fan current draw, faulty wiring, faulty cooling fan relay, check the cooling fan relay in underhood fuse box. the contacts may be burnt and sticking.

Electric fan wont kick in jeep over heats replaced thermostat and two sender units


Sounds like your cooling fan relay is bad the jeep grand cherokees are known for this, first thing i would do is unplug the radiator cooling fan and run 2 jumper wires direct from the battery to the fan connector if the fan kicks on your fan motor is good and the relay is bad, if the fan doesnt kick on replace the fan motor with a new unit, the cooling fan relay on your particular model jeep is located under the passenger headlight and requires you remove the front bumper to replace it, however some people cut a small hole under the headlight to access the relay the faster way but if your not to keen on cutting holes in your car remove the bumper and replace the relay if the fan checks out and you wont be overheating anymore...

Car is overheating, Fans wont turn on


First are you sure the fans are good. Unplug the fans and hook directly to the battery and see if they turn. One fan is for the engine and should come on when the car gets hot. The other generally comes on when the a/c system is on. If both fans work hooked directly to the battery they are good go to the cooling fan switch or temperature switch (same thing different name) and make sure it is good. This tells the fan to kick on when the car gets hot. The other one kicks on when a switch on the a/c system tells it to kick on. Check and make sure you are getting power to the fans. Get a test light and ground it to a good ground on the car and probe the plugins going to the fans and insure there is power coming to them when the car is running. If no power fuse is bad or the sending unit is bad.

1994 Saturn 1.9 SOHC cooling fan does always come on


This is actually a commen problem. All I can tell you that there is trick with pressing the A/C button while leaving the blower fan off. That will usually kick the fan in. What I find is that when you have a car that is overheating, and this is especially with GM cars, the best thing to do is to try to cruise at a constant speed, while avoiding heavy traffic, allowing the motor to breath cooler air which will stop the temps from rising any further. Most GM motors are built to handle the abuse of an overheating engine.
This suggestion is a possible solution to this simiiar problem which I had. This solution won't be any good for someone with a seriously overheating problem. If your temps shoot up high after only driving a short distance, parts or supplies will need to be bought.
