fans wont turn off after header install anyone have any idea why my fans are on the whole time i drive now? i just put on my headers and ever since then its been doing this. i replaced my temp. sensor because i broke it during the install and it made my temp gauge inop. and i figured this what was making my fans stay on. well its not.
Re: fans wont turn off after header install The fans come on by the PCM (Temperature and A/C Controls). Any SES lights/Scanned for a DTC ?. Are they at low speed or high speed when you start the car ? It sounds like if the fans are always "on" there is a short in one of the circuit paths.

Re: fans wont turn off after header install the PCM provides a ground to two relays in teh box under the hood. the connection to one or both is probably switched on by something (wire crossed or something).
