So my master control switch on my drivers side door can roll down 3 out of my 4 windows (passenger side it won't go down). So, I replaced the master switch and still the same thing, passenger side window won't go down....

However, if you push the passenger side window switch, on the passenger side door, the window rolls down with no issues....

So here is what I've done, I plugged in a 12v multi into the actually passenger side switch on the wires are reading 11v and 10v when I hit the passenger window switch from the master switch....

Any thoughts? The wires look clean as well...

Same problem with my back passenger window changed master switch twice thinking I may have got a bad one also changed back window switch still same problem checked wires and still intact although if I turn the ignition on and off a couple times it may operate the window

I figured it out. Take off that switch and clean the metal prongs on the switch. I used a pencil eraser to clean them. Worked like new!

I would try that but considering I changed the switches already no need to clean them since prongs are new

Regulator

sorry missed that… you checked all the fuses and the wiring in the door?

yeah fuses are fine wiring in the door is good but the wierd part is if the master switch isn’t working for the passenger back door the back door switch will work I can’t figure this out
