What are the symptoms of a bad cooling fan resistor?
Another symptom of a potential problem with the cooling fan resistor is cooling fans that stay on at all times. If the resistor shorts or fails, it can cause the cooling fans to stay on even when they are not supposed to.
What should I do if my radiator fan is not working?
A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.
Why is my radiator on my Jeep not working?
Caution DO NOT open the radiator cap on any hot cooling system. With that being said, one very common problem is the radiator’s cooling fan not working.
Why is my Jeep Grand Cherokee not cooling?
With that being said, one very common problem is the radiator’s cooling fan not working. Jeep Grand Cherokees that have a factory tow package will have a mechanical fan attached to the water-pump in addition to the electric fan located closer to the radiator underneath the plastic shroud.
What should I do if my Jeep Cherokee cooling fan does not work?
Check for battery voltage at terminal 2 of fan relay connector (Fig. 43). Connect a jumper wire across the radiator temperature switch harness connector. If fan operates proceed to next step. If fan does not operate replace radiator temperature switch once the engine has cooled down.
Can a radiator fan be turned on with a / C on?
Your electric fan WILL turn on with your A/C switched on, I was 100% certain it did BEFORE I went out to test it simply so I could say I tested it. So for clarification, I just tested it on my own rig, and the electric fan turns on with the A/C on.
Why is my Jeep radiator not turning on?
The fan will turn on after the temperature reaches about half. Usually comes on when the car is standing still due to the small amount of air circulating through the radiator. Too many mods to list… No the AC will turn the radiator fan on to pull air across the condensor.
What to do if cooling fan does not work?
If fan motor does NOT operate, check continuity between terminal 4 of the relay connector (Fig. 43) and body ground connections on the fender panel back from the relay connector (Fig. 42). If continuity exists replace the fan motor.
Another symptom of a potential problem with the cooling fan resistor is cooling fans that stay on at all times. If the resistor shorts or fails, it can cause the cooling fans to stay on even when they are not supposed to.
Why is my blower motor resistor not working?
CLICK HERE TO RESET YOUR PASSWORD! Help! Fan quit working on all 4 speeds. AC light & recirc light still light up and AC compressor clutch engages when turning fan on in AC mode, but not getting the fan to work. I replaced the blower motor resistor and the control unit with new parts from rockauto (ACDelco).
What is the function of a cooling fan resistor?
This is made possible by routing their power through the cooling fan resistor. The cooling fan resistor is an electrical resistor that limits power to the fan in steps, so that the fan can operate at different speeds according to the cooling system’s demands.
What does it mean when your radiator fan is not working?
This is what we call a blown fuse. A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan.

Why is the viscus fan not working on my Audi?
The viscus fan should be on all the time, Unless your self or previous owner removed it or if the viscus coupling has broken down and not offering any air movement. if you use VCDS you can test the electric fan.
If there is power indicated on high blower speed, but not low or mid range, the problem is the blower resistor. Test for ground at the blower motor if there is power indicated at all ranges, but the motor does not function.
What happens when a blower motor resistor fails?
The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed.
What happens when a cooling fan relay fails?
If the relay fails, it will be unable to supply power to the fans, and as a result they will not operate. This can lead to overheating, especially when the vehicle is at a stop, where there is no forward motion by the vehicle to pass air over the radiator. 3. Cooling fans stay on at all times
