Girlfriend drives a 03 basemodel jetta, radio wont turn on and the power locks and windows won’t work.I don’t know much about jettas or any volks , figured someone here might have a solution.
I checked all fuses and disconnected and reconnected the battery
The radio should have constant power to it. If you’re sitting in the car, and you push the power button it should come on. It’s wired straight from the fuse.
There is also a fuse in the back of the radio you can check.
The windows and power locks are separate. That could have something to do with the comfort control module, or possibly a pinched wire on the door.
