Check the thermostatic switch
There are a few ways you could make your radiator fan turn on. You could fix the wiring for example.
Which fan? Blower fan inside the car or cooling fan on the radiator?? Be more specific if you want help. If it's the blower motor, see the answer for how to do it on a 90 model. Up thru 1994 they're all the same procedure.the cooling fan
depends what needs to be fixed and how badly the parts are damaged
It could be the fan switch mounted on the n/s of the radiator. Easy job, but if you've overheated the engine there may be further problems. Phil
check the cooling fan sensor somewhere attached of the fan housing.
You will have to be specific about which fan you mean- the radiator cooling fan(electric or mechanical) or the heater fan. It might help too if state what is happening(or not)
Need more information, is the fan just not working? I would first check the fan relay and temperature switches.
The most common causes of engine overheating (in no particular order): 1) Blown head gasket - fix = replace blown head gasket; 2) Blocked radiator core - fix = chemical clean &/or radiator back flush; 3) Stuck thermostat - fix = replace thermostat; 4) Faulty water pump - fix = replace water pump; 5) Non-functioning cooling fan(s) - fix = check wiring to fan(s) &/or thermo switch; 6) Broken / loose fan belt - fix = replace or tighten fan belt; 7) Lack of water / coolant in radiator - fix = top up radiator; 8) Retarded ignition timing - fix = check / adjust ignition timing; Hope this helps!
Check the temp sensor. Also, if the AC compressor is on the radiator fan will be on, so turn off the defroster and the AC.
Before you fix the Fan Relay, look for a "RAD FAN" fuse (30 amp - orange). Normally, the computer diagnostic shows the problem is the Fan Relay, but, in my case was the Radiator Fan Fuse ($5). I waste $60 paying for the Fan Relay :-[
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Thermal relay is stuck. Replace it.
