The power window switch may fail and the windows will not raise. The main switch at the front center console is commonly at fault. A failed switch will require replacement.

I put down my front drivers side window and it never went up. I tried to toggle the switch but nothing happened. All my other windows are fine. I don't know how to get to it through the center front console
