Q: had pads and rotors installed,

The first thing to check for is any blown fuses for the brake lights. The brake light switch gets power from the a fuse and then sends power into the brake light fuse and the turn signal module. Power from...

Hi. If the window came off of the track then the door panel would need to come off to see why that occurred. Most of the time the window comes off because the regulator is failing and the window bound...
