OK I have an issue. The driver side back window will go up and down from the controll in the back seat. But when try to put down or up the window from the master controll from the driver seat it will not go up or down. The master controll will unlock doors, and roll up and down all the other windows in the truck except the driverside back window. I'm thinking this might be the switch? But switches are abotu $90 and don't want to spend $90 if thats not the problem. So how can I check to see if it is the switch. Think its funny that the other window work and just this one will not go down.

 

Could always call around see if anyone has a test switch you could try.

 

Brother it's the switch you can't really test the switch 100% unless you go to a junkyard and pull one And try it

 

its the switch, spend the $90
