Help, all the power windows stopped working.

One day they worked, 2 days later they stopped working, at least they were up. The fuses, breakers & links seem to check out. Any suggestions?

The main switch assembly may be defective. The other switches won't work without that one. Could also be something to do with the BCM. Not sure. If it's under warranty, a dealership will fix it.

Where did you check the fuses? What locations in the car?

Under the dash, under the hood toward the front (side to side w/black cover) the links on the positive batery clamp.
I checked everything electrical, they all work but the power windows.

I think you missed one spot. Check this out. It may be in your IPDM.

It was the BCM, replaced under warranty. Two days later the windows stopped working again.
