so my 3.8 camaro is running really hot.. i noticed the fans wont turn on unless i use the a/c. i replaced the relay but still no luck and i was told to replace the cooling fan switch but i cannot find one anywere.. do the fans even have one?... also i heard that the temperature censor controls both the gauge and tells the pcm when to turn on the fan?

 

Yep its your coolant sensor that tells the fans what to do.

 

thanks ill try that and update
