Have a problem with my passenger side power window. Using the driver side switch I cannot operate the passenger window. The passenger switch works fine and operates the window up and down every try. I replaced driver side master switch and no change. Help please!

 

Depends on the year of your truck. The '97-'98 uses a relay that's in the fuse panel (taking it out, and giving it a whack freed mine up). Check the contact of the plug going to the switch assembly, and spray it with Contact cleaner.

 

its a 99. does it have a relay? is it in the interior fuse block? i have cleaned all contacts in both doors and bought new driver door switch. passenger switch works fine

 

I haven't messed with a f150 window switches but have on outher fords. The passinger switch has contacts that disable the outher switch while it is in use. So the passinger switch could be at falt.

 

Ok I got ya. Even though it works it could be causing the driver side to not operate

 

Bought a switch for passenger side off eBay. 12 bucks. Driver side works now. Problem solved!
