I have a 1998 ford escort lx SOHC. my cooling fan is not kicking on when i am idling and my car starts to overheat. It cools down if i am on the highway or constantly moving, but it cools down below operating temperature, probably down to around 1/3 of the way up the gauge instead of around the normal 1/2 on all cars. I changed the thermostat, it was broken, this did not fix the problem, it is still doing the same thing. Is there anyway to tell if it is the fan or one of the sensors, or maybe something else.

it cools down cause the air flow when driving, either the relay is bad, the fan motor is bad, or the wiring. Try and turning on the AC if you have it, if that doesnt work, jump the motor by using a wire from the negative terminal on the battery, if it turns on, then i would say the wiring is bad, if not, the motor

Unplug the fan and run jumper wires straight from the battery to the plug if the fan runs the motor is good. Be sure to stay clear of everything in case it comes on. The relay for the cooling fan is part of the CCRM.

The ac does not work, not sure if it needs a recharge or is just broken, never really looked into it. I have a multimeter and checked the voltage coming from the fan connector so i think the wiring is good. Why does the temp cool down so much from the airflow, it has never done that before? it has always climbed to operating temp and just stayed there, i haven't seen a problem until now because it got a little hotter outside. Could it be the ECT sensor at all?

could very well be the ect sensor or the low-speed relay inside the ccrm that is bad

even if the AC doesnt work, it should still turn the high speed fan on to help keep cool during the extra load. If it does come on then its the low speed relay, be it inside the CCRM or not. if it doesnt turn on then wiring is bad.

i jumped the fan directly to the battery and nothing came on, so i am guessing the fan motor is burnt out, when i switched the thermostat that was broken too, so maybe it got stuck partially open and ran the fan constantly, and it eventually burnt out, but hopefully a new fan will solve the problem.

so i got my new fan in the mail today, took about a week and a half to get here, installed it, turned on the ac and it kicked on, hopefully when i drive it later it will kick on without the ac's help, but now i have a car with a functional cooling fan. thanks for the tips
