Hopefully somebody can give me some advice cars overheating cooling fans aren’t kicking on. They only turn on when I turn the ac on and turn off after a few seconds. Verified fan switch is good, relays and fuses are good. I even jumped the fan switch connector with a paper clip and the fans don’t turn on when I turn the key over or the car on. I verified the fans were good I was able to power them on with a 12 volt battery. I’m thinking maybe a loose ground idk I’m running out of ideas
