Just recently purchased a 93 STS. All power windows work with their own switch but driver's switch doesn't work any of them. Replaced with one off of e bay but situation still the same. Mirror adjustments work with switch and other windows only work with switch hooked up. Is there another breaker or fuse for window switches on drivers door or??? Maybe I got a bad switch from e bay. Ideas anyone?

 

Drivers door switch is part of ground circuit for all windows to operate. If switch is unplugged no windows will work. Check for 12v on pink wire to drivers window switch. Circuit breaker for windows powers up all switches so it is ok. No 12v to switch check wiring in door jam area for broken pink wire.

 

Thanks I'll start tracing it back.
