Question about 2002 Jeep Grand Cherokee

1 Answer

I just had the radiator fan relay replaced today because the fan would not shut off when I turned engine off. I had to pull fuse to stop fan.I Stopped for gas on way home from shop. When I restarted car, the check engine light was on? I checked under the hood when I got home in garage and It appears that the radiator fan is not working? Any idea what is going on? The new relay failed? The repair shop was closed shortly after I pick up vehicle so I can't report the problem until morning.

    Thank you for the feedback. I Just rechecked the fuse and it is not burned out. So the faulty fan may be the deal... overloaded the new relay. I also was reading a post elsewhere that suggested use of a heat condutive compound should be placed between the relay and it's mounting location. I will have to discuss both these items in AM with the repair shop.

It sounds as if there might be a burned fuse. instead of replacing the rad fan relay i suppose they should have looked further. I'd be willing to bet they would find a faulty fan which in turn is taking out ur fuse or relay. With a faulty fan, it will require way more current to get it going then normal, overloading the circuit, blowing the fuse, or even, over loading the relay. I would be willing to bet now, you have a burned fuse due to a faulty rad fan.. good luck

Cooling fan won't shut off


Hi!
Check the cooling fan Relay located on the engine compartment Fuse n Relay Box, it is probably stuck ON. If fan stops when relay is removed, replace relay.
Note: Some vehicles are equipped with automatic cooling fans where the cooling fan can come on when engine is hot, even if the key is OFF or not in the Ignition, check your owners manual.
Good Luck! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Radiator fan won't shut off


Go into fuse box and pull out cooling fan relay this will stop fan.
Then check coolant temperature sensor(CTS) for resistance. You gonna need shop manual for this.
If sensor doesn't match up with resistance spec's replace. If it matches with specs then the only two items left are the relay you pulled and the wiring in the circuit. Test relay for shorts. Back probe wiring for shorts also. Good luck Its usually the relay. But I have replaced CTS's also.

My 1999 plymouth voyager van's radiator fan constantly on


There is a fan relay in the fuse box in the engine compartment. Usually that is the reason why it won't turn off. It fuses in the on position. If you have the manual it will say which one is the fan relay. just pull it out and get a new one. They are not expensive.

Hope this helps

My radiator fans both have stopped working


Could be a few things. If your fans were just working then just stopped, it could be the fan motor. It could also be the relay. If you know where your lo speed and high speed cooling fan relays are located, you can eliminate this step easily. Take a known working relay (rear defrost or something not essential for starting) and replace the fan relay with the known operational relay while your engine is running and A/C is turned on. If the fans start, there's your problem, if not, then it's probably your fan motors.
Make sure the fuse that protects the fan speed relays is not blown as well.

Find relay and give it a tap, to see if that helps. Not sure on that if its along drivers fender under hood or not, but listen for click from small 1"x1" roughly relay attached somewhere in engine compartment area, firewall, fender area.
