It started with my window not rolling down and the motor not even making noise, and then last week the power lock buttons on both doors up front no longer work. But the passenger side window still rolls down and the other windows roll down from the driver side switch. Just curious if it is a known problem or just my problem?

It sounds like the main window switch is going out but to be sure we need to check the power and grounds of the system here is a guide to help and the window and door lock wiring diagrams below so you can see how the system works and which wires to test.

Here is how to change the main window switch out as well in case you need it. Start by checking the fuses. Check out the images (below). Please let us know what you find. We are interested to see what it is.
