What you can do first is locate the accumulator. This is located in the low side hose near the firewall. Looks like a big canister with a hose out each side at the top. There is also a switch between the hoses. (example would be one hose at six oclock the other hose at twelve oclock and the switch at three oclock.) Unplug the switch and using a paperclip jump together the two wires in the connector you just unplugged. Do this with engine running and a/c on. If when jumped the compressor kicks on then your a/c is low on freon and needs to be charged after fixing the leak. Hope this is helpful.

Troulbleshooting radiator fans


try hitting radiator fan motor with hammer (not extremely hard, just rap on it a few times) with the engine running and ac on. if the fan comes on the motor is bad. if that dont work it must be tested for power and ground supplied to the fan from relay (power is supplied from the relay). does the ac compressor come on? is it overheating? the fan is controlled by the powertrain control module and a scantool would be needed to see if the module is turning the fan on.

Some cars have a thermostat that tells the fans when the water temp reaches a certain temp then the fans start. Or the relay that starts them could be bad. You may find the relay and switch it with another like it and see if that works.

The red wire with black strip should be positive and brown should be neg. The middle wire is the control wire. Unplug the connector and take a cig lighter and heat the wire above the plug. Peel the plastic back to expose the wires. NEVER cut anything! Get two long peices of wire and loop them around your battery posts. Just touch each wire to the two wires on the fan. If the fan turns on its ok! If you dont want to go to the stealership, you can run a toggle switch under your dash. Just loop the two fans together and leave them unplugged. This will buy you some time untill you can get someone local to look at it. On hot days, just let it run! Better to leave them on then to forget to turn them on.

The fan is controlled by a relay that could be bad, and the relay is controlled by the climate control unit, which could also be bad. Pull the fan relay and see if it the primary is getting voltage, with a test light, when the AC is turned on.

Where is the cooling fan relay located on a 1997 ford escort lx. Replaced the fan and it worked for a few minutes then the car ran hot and the fan would no longer work.


This car has a relay module that contains a few relays internally and cant be serviced the relay box must be replaced, the relay box module that contains the fan and ac compressor and fuelpump relays is located under the air filter box, remove the filter box and you will see the relay module bolted there. hope this helps.

Fan will not kick and wants to overheat.


I assume since it is a GT, you have ac. If you turn on the ac to max with the car running the fan should turn on no matter what the temp of the motor. If it does not, warm the motor up to OT(operating temp). You should here the fan relay click when it wants to turn on. If you dont here the click you might want to check the relay. A seperate fan relay should be under the hood in the power dis. box. It will say what relay it is. If it clicks, you might need a fan motor.....
