I'm having a problem with the windows none of them will go down or up from any door. I changed the switch, checked wires in door jam and all fuses seem to be good. The door locks work and the power mirrors work and the speakers work, just not windows. Any ideas? Thank you for your time.

If none of them work, it sounds like a power issue. Did this happen all at once?

Okay, to start, we need to check two things. First, picture 1 shows the fuse for the windows. Confirm two things. First, is the fuse good, and second, is there power to the fuse.

Next, there are two grounds I need checked to make sure there isn't a corrosion issue or something has broken. See pic 2 for locations.

Here are a few links you may find helpful when testing:

Since none of them work in either direction, I suspect it is a fuse related issue or an open circuit between the fuse and switches. Let me know what you find or if you have questions.

Take care,
