Aux fan not coming on, relays look good, what to check next?
I noticed that the air coming out the the ducts was getting warm, once I stopped at a red light for more than a minute. Once moving again, the air was nice and cold again (cold enough to give me an "ice cream headache". So, I figured I need to check if the fans are running. ... Nope. Then I checked the fuses....All of them are good. Then I took of the relay cover, and eyeballed relays B and C. They looked good too (including the fuses. I even took the relays apart...they still looked good.
Now I have come to the end of my rope.
I did notice that the fans would come on once the engine temp. was way up there (around the 100° mark)...but that doesn't help me any when they turn back off.
What should I check next?
(on a somewhat related note... Once I pulled off the relay cover, the largest module there (it has a 126xxx part#) had a hole on the top of it... as if someone had pushed on it, and broke the plastic. Is it imperative that I cover this hole? and if so, with what? electrical tape? JB weld?) thanks!
thanks for any help,
