90’ audi 100 power windows & sunroof problems. have replaced relay switch & it runs both & still dosen’t work. they worked before, except that you couldn’t roll up or down the left rear window, by either switch; the right rear wouldn’t go up or down with it’s switch,but would with the drivers switch. now nothing at all from p/w or snroof. so is there anything i can do to fix it without high cost of a dealer’s shop?

I would check for power getting to the circuit. It sounds like a fuse may be blown somewhere. Use a test light to test with.
