For the 3rd time this month my power windows stopped working so I pulled the fuse and replaced it. My driver side window worked but my passenger side didn't. Then I realized that my Alpine Head Unit and interior lighting stopped working.

This morning while pulling through McDonalds the driver side window wouldn't roll down. So I'm stuck with no radio, no lighting, and no ability to roll my windows down. What can I do to diagnose what the hell is wrong and how can I get everything to work again?

 

The most common reason for a fuse to blow is a short - plain and simple. A bare wire touching metal, two wires touching each other - that will do it.

With your problem, I'd be suspicious of either a car alarm or a previous owner's car alarm install. Many alarms tie into the power windows so you can roll them up/down with the remote.

The majority of electrical problems are caused by people messing with the electronics. Car makers do a pretty good job designing eletrical systems so they don't short out and cause problems.

Fortunately the power window circuit is pretty basic - if you pull the door panel off, you can most likely find the problem there.

Alright. I'm planning on taking my car to a reputable car accessory shop that works on alarm systems, audio systems, and all that good stuff. So hopefully they can remove any crap thats in there that can or will be causing problems. I'll look for a short for the power windows. But what about my problem with my interior lighting and head unit?

 

Ok, here's another thing. Everytime I shut off my car and turn it back on, the trip meter goes back to 0.0

Hope that helps someone get a idea of what could be wrong

 

Please help
