hey


my cooling fans are coming on when the car is off and cool....and its killing my battery....does anyone have an idea as to why

 

I'm no expert on the fans, but I'd imagine it'd be one of two things. Either a faulty thermoswitch or a short in the wires somewhere.

I hate shorted wires so much....

 

how would i fix a short?

 

Could be that one of the relays is sticking.

 

The problem is finding the short to begin with. Get a copy of the wiring diagram, a multi-tester, and a large dose of patience. Once you find it, you just need to clean up the wiring.

One item to may want to check is that the black wire coming from the ECU that is commonly used for the Fan Mod could be grounding on something causing the fan to come on. It would be an easy fix if this was the case.

 

where exactly is that black wire?



and does anyone have the correct relays i could by off of? or the part number?

 

right by the ECU

 

my car is doing the same thing. Looking at the relays first then messing with the wiring next.

 

mine did that for a long time. None of the fixes on here would do it so I cut the fans from running automatically and ran a wire to the test box fromthe interior and turn the fans on manually when I turn the car on. It's ghetto but it works.

 

Isnt that a solution for a TSB anyway? I wouldn't say its ghetto.
