passenger window switches only roll down any ideas?

Asked by Craig Jul 09, 2023 at 09:16 PM about the 2007 Chevrolet Silverado 2500HD LTZ Crew Cab 4WD

Question type: Maintenance & Repair

I have a 2007 Chevy 2500hd,  driver side master window switch works fine to  
roll all windows up and down.   Front Passenger and rear driver window  
switches will roll down but not up,   Rear passenger switch doesn't work at all.    
Fuses look good and I've replaced the driver side master switch but still have  
the same problem.  any ideas?

Front passenger door is most likely the window switch, if it goes one way but not the other it’s a switch. The rear door is another matter, you need to get to the switch and see if it has both power and ground and it switches when changing directions, if the switch checks good then remove the door panel and test the wiring to the motor if the wiring test good then the motor is toast. If that the case then replace the entire regulator assembly.

I haven't ruled out a broken wire yet, but no evidence of a rodent, and door locks work fine, I would expect problems with that if a rodent was chewing on the wiring.

Thanks GA that's kind of what I'm suspecting just odd to have all 3 doors act up at the same time

Things just happen that way. The newer they are the more strange things happen.

Just a quick note to end this post, swapped switches from side to side and the switch that didn't work at all didn't work on the other side and the down only switch was down only. Tested continuity thru the switch and it only activated on down. Replaced all 3 switches and problem fixed. thanks for everyone's input
