I have a 1993 F-150 XLT. The first problem I need help on is that I can't lower the passenger window from the drivers side but I can put it up from the drivers side. Does anyone know how to repair this? Another thing is that the bench seat moves back and forth and doesn't seem to stay in place but the drivers side stays fine. If anyone could help me with advice on these it would be greatly appreciated

 

So you can raise and lower the window from the driverʻs side, and raise only from the passenger side?

Could be switch on passenger door, wiring or grounding issue.

Look for damaged or worn seat parts, even obstruction where seat latch makes contact with seat mounting

hardware. The seat parts can be ordered from MANY FTE sponsors.

 

There is a wire, that goes from the drivers side lever, to the pass side to activate the latch. Mine came off, and the pass side was hung open allowing the pass side to roll free. Plus, spray the bejesus out of the moving parts while you have a look-see under there...

If anything, 4 bolts, a nice day and a beverage to remove seat for a better advantage and spring cleaning ta boot...

 

From the driver's side, the driver window is fully functional but the passenger window CAN NOT be lowered from the drivers side, only from the passenger side.

 

I'd want to take a look at an electrical schematic beforehand, but it's likely your passenger windows switch on the driver's side is bad.

 

Ok, so can I just buy an entire new window switch?

 

I'm sure you could Google that, or call LMC Truck and see what they got.

Or just do what I would do and go to the junkyard for one. Bring a multimeter and test the switch from the donor before you buy it.
