power windows

[Kurt Harmon]

I have a 1985 GMC Sierra Classic with power windows. The passenger side window goes up and down fine with the driver side switch but will only go up with the passenger side switch. New switch and motor. Any ideas? HELP

Could be broken wire in the door jamb. Welcome to GMSB

I actually had a switch fail that way, but I’d check the wiring first, as it was suggested.
