94 XJS Rear Window Problem Solved
Kudos to Paul for pointing me in the right direction. Left quarter window would not go down with the top, problem being a faulty thermal switch, once I found it, thanks Paul. The diagrams and information results did not mirror my XJS. Reading past threads on the operation of lowering the top, my XJS operates by lifting the brake handle and pressing the top down switch. As the top goes down the rear windows go down and are totally lowered before the top is lowered and reverse, the top starts up, side windows go fully raised and the top comes to rest in the fully raised position. As problematic as these Beauties seem to sometimes be, they are well worth it. "GOTTA LOVE'EM" Would be remissed if I didn't mention the wonderful job the entire Forum Staff is doing. Thank you all and we appreciate the hard work you guys do for us.

Seems as this had been worked on previously. The breakers were laying behind the tray and not attached.
Thanks again

My relays were not attached. It appears that they(2) are mounted to the bottom of the tray under the 30 amp fuse. My breakers are black, thin and measure app. 1"x2" with 2 push on wire terminals. One operates the left window and the other the right.

1995 Jaguar 4.0 Convertible - Rear Window Thermal Switch
Hi guys,
I have the same problem as many, a stuck rear quarter window. I've checked the relays and nothing seems wrong, checked the fuses and all is good. Now a couple of posts have mentioned a thermal switch, where are these located? Looking at the wiring diagram I can see there's one for each quarter window. Is that right? I can see one on the rear tray below the relays, but not two together. Any guidance would be much appreciated.
Many thanks
Paul

As I stated, mine were removed from the tray, but it appears the two thermals are fastened to the tray back to back, meaning, there should be another thermal behind the one you are seeing. Another strange set up, tight area. Hope this helps.

I had my 1994 XJS 2+2 to the mechanic today regarding issues with the rear quarter windows and the top. He told me that there is no power to the top switch and that he had no idea how many shop hours it would take to track down the short. I thought i'd bring the car home and see if perhaps I could save a bit of cash by trying to locate the problem myself. It seems from looking at the wiring diagram and reading the posts that the thermal breakers might be a possible solution. Can anyone post a pic of what these look like? Should these test zero resistance across them like a fuse if they are working properly?
Thanks
Thanks
