Hi I have an 1995 jaguar xjs, the drivers side rear quarter window does not work and is stuck in the up position. The relays are good. But I am not getting 12v on pins 86 and 87 for both up and down relays for the drivers side.

I believe I need to check the thermal breaker? How/where do I check to see if my thermal breakers are good?

passenger quarter window works as it should.

Where is the thermal breaker? And how do I test it?

 

Have a look at this thread which may help.

After some more research, the thermal breaker is the black rectangle under the 30 amp fuse. The other thermal breaker is right behind that one. Now I need to figure out how to gain access to it? I don’t see any obvious way to get to it unless I had baby hands.

 

turns out the thermal breaker was bad. I was able to plug the connectors into a 30 amp fuse to get everything working as normal.
