I put new switches and changed the relay behind the glove box, and my passenger window still works once, then stops, as if there is a bad relay. I've cleaned the brushes on the motor, works back and forth when out of door (no load). Is there another relay...one for driver motor and one for passenger? If so, where is the other one? Driver side works fine.
Thanks

 

Um, what model XJ we sorting

Your profile has a 340 MK2??

 

Profile updated...my XJS V12 is quite "altered", see attached photos. I tried to make it look as if it was 1973, pre big bumpers!

 

Have you tried sliding the widow up and down without the motor engaged?
The linkage and tracks are easily fouled or mis-adjusted.

 

No.

One relay and one circuit breaker for both windows

Thanks. Where's the circuit breaker and what does it look like?

 

From memory the breaker is at the RH component panel below the glovebox, near the power window relay. It'll look like this:



But I don't see how it could the be the problem. You say the driver's window always works, and both windows are on the same breaker, so.....

did the window get stuck half way down? Then never works again? Does it make it the whole way down?

 

It sometimes does stick, I guess it's time to pull everything out and have a good look at the guides, thanks everyone.

 

Smart move, time for surgery.

Waaaaaay back, before computers and Forums, my Series cars had similar, and I found the small wheels on the regulator inside the channel, were failing to rotate, old age. Jamming the whole shooting match.

Same with the XJS, mainly the Red one.

Took the old wheel to the hardware store, looked in the "sliding door" section, they had staff that knew what they were doing in those days, and found what I wanted. OK they were Blue in colour, the original were White, The car had no idea.

Cost me $1 per wheel, from memory.

 

Can I just say that that is about the most beautiful XJS I've ever seen? This is very close to the look I'm going for with my own car, except I am keeping the chrome blades and deleting the tubes for the bumper shocks.
