I have a Sierra Sapphire 1992. Niggling problem is that whilst for over a year the electric front windows have worked fine, today the passenger one would close but not reopen. Driver side works fine. I have checked the connections on the back of the switch and sprayed the switch and motor with WD40. But still no luck. Anything else I can check or try please? Don't want to buy a switch and the motor for the window is at fault or the other way around.
Thanks for any helpful suggestions.
