Fan Still Doesn't Work - Tried Sooo Many Things

davio8 · Post by **davio8** » July 5th, 2007, 5:07 am

Hey guys
So i realized my coolant has been leaking from the top, which then i noticed my fan would not turn on. I tried so many things and it still doesn't work. Ill list them:

-changed radiator cap
-changed thermostat
-changed oil filter
-changed engine coolant temp. sensor
-connected fan to battery, and it worked
-tested the fan relay as it says in shop manual and fan relay works
-flushed out all coolant and new clean one is in

Thats all I can thing of that I can do. I don't wanna send my car to a mechanic and gotta pay 200 bucks on something I could've done myself. So anyone got any other ideas I can try?

Thanks a lot

Isn't there a fuse for the fan?

are you sure you replaced the correct temp sensor?

Well what are the possibilities? Fan motor, relay, switch, fuse, Temp sensor. ECM or wiring, right?

When I have my ac activated both fans run.

why dont you wire it to the battery and see if its the fan? If all fails. wire them to a switch. I got both fans wired to switches. For drag racing (at the line) I turn both of them.

Try cleaning the connector right next to the fan - use a small file to remove all corrosion and spray on some electric cleaner and then apply di-electric grease to prevent further corrosion.

if the fan works jus hard wire the fan to a manual switch

thanks guys for the input

ill try cleaning the connecter but i found the problem. there is no electricty running to the sensors. all fuses are good, but anyone know if there is any hidden fuses in the middle of the wiring anywhere?

thanks

i dont know if ts for the blower motor but there is one near he fusebox in the car. its not really a fuse, more of a breaker. it should say FAN 30AMP on a small rectangular box.
