the thermostat will make both fans become idle if it is not opening. this happened to me on my 95 3.1 lumina
Check the relay.
If cooling fans stop working and engine runs hot wtih A/C on usually excessive head pressure will build in a/c compressor and refrigerant will discharge from system. cooling fans may have a bad fuse or relay should be repaired prior to recharging a/c
Blown fuse, motor burnt up, or the fan relay switch is bad.
A normal puddle on the road should not damage the fan. If the water is deep, then water could get inside of the fan connectors or the fans themselves, and cause failure.
Cooling fans won't stop running in the cold on a grand am gt 2001
If the radiator cooling fans are not working - those are the first things I would check out. It is possible that they may be the heart of your problem, and the remainder of it (the A/C stopped working) might simply be a 'fail-safe' to protect the compressor. Start with the fuse and/or relays controlling the fans to see if they're good or they're blownl, and then the temperature sensors themselves (that are supposed to activate the fans into motion).
Figure out why they stopped working and repair the problem.
Cooling fan not working, or your cooling system needs a complete service. The cooling fan should be on continuously when the A/C is on.
if both fans quit working, it could be as simple as the relay fuse going out. have your mechanic check these fuses.
Check coolant levelMake sure coolant fans are workingReplace thermostatHave radiator boiled out or replacedMake sure system is not airboundReplace radiator capMake sure water pump is working properly
The cooling fans will run when there is a signal calling for them to come on. High temps will do that. Also anytime the ac is on, a fan will run. Try turning the ac off and see if one of the fans stop. Do this when the engine is cold. If the fans run anyway, check your fan relays, they may be stuck on.
Be sure the cooling fans are functioning when the ac is running.
Hi, If the cooling fans run for a few minutes after turning off the engine and then stop, the engine computer probably thinks that the coolant temperature is very high and is trying to cool that off. If the fans run on and on and do not stop at all, then I would say that you have a shorted control relay for the fans. So a little troubleshooting is needed for this issue. I have provided a link that describes how these fans are supposed to work and how they are controlled. Good Luck, Greg
check radiator cooling fans not working. Will turn on automatically when the proper temp is reached. Fans should go on IMMEDIATELY when the A/C is used. Set temp to 65 to test
To make the contraceptive implant stop working, have it removed. You will have immediate return to fertility.
Usually when fans stop working it can be contributed to the heater blower motor resistor which is either located in the heater duct underneath the dash or under the hood next to the blower motor.
Two different circuits---the fan has a fan switch, and the gauge has a sending unit...also, the library should have a shop manual...:)
Yes, of course a cooling fan would help, that's what they are designed to do. Ask the sales representive at the store to explain to you how they work.
You stop driving it and repair the problem that is causing it to run hot. A complete cooling system service is in order. Drain the coolant, replace the thermostat, replace the coolant, check the function of the water pump, the thermal switch for the cooling fans and the cooling fans themselves. Clean the exterior of the radiator and flush the radiator.
some times the fan will not work if the radiator fan sw is bad. this is like a oil presure sw when it get to the right temp the fan sould start up. it is loc on the side of the radiator.
The ac compressor's clutch may be blown. If so the compressor will not spin and provide air. The fan could also have a bad motor which will stop the fans from working.
It doesn't. You must have a Wii hardrive or cooling issue. Mine did and it was the only game that stopped working.
I had a problem with the cooling fans not coming on when the car was at rest.... so when i would stop at lights the temp would start rising... i ended up working out you can override the faulty circuit by turning on your a/c when you pull up and that overrides it and they turn on and no more over heating..
the fan can be installed backwards and moving the air through the radiator in the wrong direction.The radiator or cooling ports can be plugged if a stop leak has been used on the engine.the water pump might not be working.
