Replaced the driver side power window and everything was working fine. Then I was driving and rolled the passenger side window down and up a couple times. Never all the way down until the end of the day. Now it won't roll up. The power lock switch works for the driver side door but the passenger side lock does not work. Seem to have lost power in the power window and lock. Where do I start?

 

Pull the switch panel out and use a test light to see if any power is coming into it. If there's power getting to the switch the switch is bad. If there's no power getting to it then check the fuses. If the fuse is good then you have at least narrowed it down to a loss in continuity between the fuse block and the switch. At that point just trace the wire starting at the fuse box and check for power all the way to the switch. You'll eventually find where the disconnect is.
