Passenger window goes up and down with driver switch but not with the passenger switch on F150. Cleaned and adjusted switch on passenger side but still no go.
Check the window security lock on driver's side to make sure it's not locked. If not clean the contacts on driver's side they go through driver's side before going to passenger. (interlocked)
Security lock not on. Switch on driver side works fine for passenger window.
Yeah but drivers side switch has a set of contacts for passenger's side to work. U need to clean contacts or replace main switch, which is driver's side. Without driver's side the passenger won't work, that's what I meant it being interlocked
