I've noticed that when my car has run for awhile and the temp. needle rises above 90 and near 120 and I'm expecting the aux. fan to kick in, it doesn't come on. I,ve check the fan to make sure that it works(by jumping it to the fuse box and it does work).The fan seems to not be getting power. I've checked all of the fuses, they seem to be fine. Can you tell me if there,s a relay somewhere that I can check?
