Thread: Why in the heck is my power window circuit breaker keep overloading!!

Ok Great! Thanks for the info!

I had the same thing happen with my 2003 Yukon (maybe the same setup?). I would blow the relay intermittently, and I couldn't figure it out for the life of me. I ended up taking it to the dealership. Apparently the passenger front heated-seat element would short out whenever someone sat on the seat - blowing the relay that included the power windows. I'm not sure if your car is wired the same, but I would try unplugging the power seats and see how long you go before you blow another relay (if you have heated seats). Good luck - I too hate electrical gremlins.

Buddy you hit the nail on the head! As soo as I started trying to remove the rubber boot that insulates the wires I immediately hear the relay start to buzz and make a cliclimg noise as if the relay was opening and closing. Unfortunately, I wasn't able to get it off and troubleshoot further because I got called away to do something else. I will keep you posted when I get back on it first thing tommorow morning. Thanks for the awesome insight!

You were exactly right! Finally got my window problem fixed and yes it was a loose wire that was shorting out inside the door chasis..
