Cooling Fan Stuck On
About a month back my girlfriend got in an accident. Didn't appear to be any mechanical damage, just needed a new fender, bumper, headlight, and hood. Anyways, she mentioned that her car is "loud" when she drives and upon looking under the hood, the cooling fan is always stuck on.
I'm not sure the cause of the problem, so far what I can think of in terms of possible causes are
- Fuse (but this would most likely make cause it to be stuck off right?)
- Relay (Could be stuck open)
- I hadn't been able to locate a single relay, but instead a constant control relay module underneath the air intake.
- Temperature Sensor
I have been leaning towards the fuse not being the problem. Figured a fuse problem would instead cause the fan to be stuck in the off position.
It seems that the temperature gauge is reflecting the correct temperature, as it is at C when the car is just starting and maxes out at the midway point. Seems that this wouldn't likely be the problem to me then (unless there are two separate temperature sensors, one going to the fan control module and one going to the gauge).
Would the constant control relay module be a likely culprit? Anything else you guys can think of?
Thanks for any help in advanced.
The car is a 1998 Ford Escort.
