Radiator fan Not working!

**jatnguyen** · 11-20-2007 06:50 PM

I've notice that my radiator fan is not turning anymore....
Even when i turn on the heat or a/c (cold) the radiator fan does not turn on at all.

On a longggg stop and go traffic, it would overheat!

what should i look for? fan relay/switch? location? or is it a coolant temp sensor by the radiator?

There is a sensor mounted in the lower radiator hose. That one is tied in to the fan relay.

2nd old guy, also the cooling fan control module fails sometimes. It is the silver box on the top side of the drivers side fan. If the fans don't come on when you turn on the a/c then I would say that the Cooling fan CM is your problem

Silver box on the top side of the drivers side fan...., I saw that box, its had fins on it. Guess i'll replace that this weekend.
Where is the relay located?

Check the relay first, it's in the ECU box, left end of plenum under the windshield.

i called the dealership today and they want $251 for the fan control module...ehhh
i'll check the relay tonight, hopefully its clear on the top of the relay so i can see if its still good or not!

How do i check to see if the Relay's in the ecu box are working?

Mine failed too... luckily I was under warranty at that time. Seems to be happening alot lately... they should recall that sucker.

Did you check fuse number 4? It is a 5 amp fuse.

Are you chipped? I had the same problem and it had something to do with the software on my APR chip. They reflashed it and everything started working normally again

**jatnguyen** · 11-28-2007 08:07 PM

not chipped, and there is no fuse on number 4.

Is there a website online where i can purchase the "coolant fan control module"?????????????

I dont feel like paying the dealership haha

Replace the Coolant Fan Control MOdule today ($250), now the fan works.....=)

Next is to install my t-bolt clamps so the piping for the fmic stop popping off
