Hi Everyone,

The passenger's side and the rear passenger's side windows on my 1985 XJ6 don't work. I bought new switches, but that didn't work. Both front and rear window switches don't work. I couldn't find any fuses related to the windows. I'm assuming there must be relays instead. Does anyone have any advice on what I should do?

Thanks!

 

A relay (extreme right side of dash, to the right of glove box) feeds power to two circuit breakers.....one breaker for left windows, the other for the right windows. If *any* of the windows are working the relay must be OK.

The circuit breakers are below the glove box (from memory here). You can check for voltage in/out with a test light. Or swap the breakers and see if the problem changes sides. Or use a jumper wire to bypass a suspect breaker and see if the problem goes away.

The breakers are about .75" square with red/slate wires

Thanks! I'll check this out when I get back to the car. Will let you know if I run into any problems.

 

Is the sunroof a cable system? I can hear the motor running but it wont open or close anymore.

 

Yes, cables.

The cables may have come adrift from the motor. Remove the rear seat for a look-see. There was a recent thread about this.

Back seat? The sunroof is in the roof, and I have dropped the headliner but the motor and all other parts are encased in some kind of box.

 

I am vaguely aware of that, yes




What year and model do you have, and was it originally built with a sunroof?

Series III sedans with an original sunroof used a cable drive system where the cables ran down the C-pillars to the motor....which is mounted on the bulkhead behind the rear seat.

Edit:

If you have a Series III sedan and the sunroof motor is in the ceiling, it's an add-on sunroof

I have had the backseat and c pillars out and I didnt see anything like that, then again though that wasn't what i was looking for when I had them out. But when i pulled the headliner there was a black box mounted to the ceiling and the sunroof slid inside of that, and I didnt see any cables running out of it.

It's a 1986 SIII XJ6

 

I very strongly suspect you have an aftermarket sunroof of some sort.

Sometimes an installer will put some sort of identifying label in the glove box or door jamb.

I would be unusual for an '86 to have an aftermarket s/roof, though. Can you post some pics?

Cheers

Yeah I can do that
