Question about 1991 Ford Escort

1 Answer

I have a 91 Ford Escort cooling fan problem. The cooling fan does not come on, but when I unplug the temp sensor the fan works. I replaced the sensor and the fan still does not come on when the car reaches high temp.

New coolant fan and new control module but coolant fan does not work on my 2002 ford escort zx2


Try checking the fuse box under the hood. It should have a fuse marked cooling fan or cooling system. If the car does start, that means the computer isn't out, but maybe there is a bad relay by the fan or in the circuit or even the temp sensor may be bad. The fan won't run until the temp is high enough; usually by the time the thermostat opens.

The electric cooling fan would not shut off so i unpluged the fan then plugged it back in the next morning and now it wont come on until i unplug theheat sending sensor 99 escort 2 liter automatic


Sounds to me like the fan relay stuck on in the first place. Are you sure that the coolant is getting warm enough to turn on the fan? Most cars don't turn on the fan till the coolant gets to 226 F. You might want to change the sensor if this is the case. Sometimes the sensor wont read high temp's. We know the relay and the computer are working now because the fan comes on when you unplug the sensor.
Post back if you need to know more about the system.
Have a nice day!!

Cooling fan not working, overheating


Replace the cooling fan relay switch. On the engine Coolant temperature Sensor make sure the sensor wire is still pluged into sensor and there is no damage to the wire in that area. If the wiring looks OK and was still pluged in then replace the Sensor. If you have allready figured out that the relay and the temperature sensor are OK. Key Off, then unplug the Cooling fan (near the fan) from the engine wirring harness.Run two wires from the fan plug directly to the battery, place one wire to one post the other wire to the other post. If the fan comes on then it is Ok if it does not come on then replace the Fan. Good Luck and have a good XMASS.

How to install a coolant temp sensor in a 1995 ford escort


The coolant temperature switch and fan control switch are located sie by side, mounted in the steel portion of the heater hose that runs from the thermostat housing to the firewall, it is underneath the air intake tube and the ignition coil pack, mounted to the back of the cylinder head. Either drain out some coolant or be very quick, and you can unplug and unscrew each switch from the hose and replace it with a new one. Make sure the engine is cold. After replacing make sure to check the coolant level add as neccessary. The single wire connector switch is for the guage, and the other is for fan control. Hope this helps, let me know.

Over heating


You may want to check first if you are loosing or have inadequate water or cooling fluids on your radiator. There may be a leak or the radiator cap may no longer prevent the steam from escaping. check the radiator fans if they are turning. You can check the fan if it is working by pulling out the temp sensor at the lower radiator hose near the engine. The fan should blow at full once you unplug it. Check also the water pump in the engine if there are leaks. You may have it replaced.

Cooling fan module???


cooling fan module just refers to the fan, the motor and the shroud. There is no electronic module.
The fan has relays for protectin and the engine computer oerates it when it gets siganls from the engine coolant temp sensor, the A/C being on, etc.
what is your issue?

The cooling fan doesnt work on my 91 honda accord


  1. Cooling fan Relay
  2. Engine temp Sensor
  3. Cooling fan itself
  4. If While A/C is on Fan does not come on I would Check Fan By unplugging it first than apply Pos+ and Neg- to it if it comes on that's eliminated Then go to step 1-3 one of them is bad I usually replace Engine temp sensors no mater what they are Crucial components for the safety of the Engine.
