Wow what a lame reply! I own this demon car 1989 Jag XJS and do battle with the Lucas wiring daily. So. If the top is raising and lowering like it should, 1st - check the convertible top pump and fuses. They are hidden away behind the seats (open the storage compartment) on the passenger side. Is anything leaking? Theres a 2 blade fuse, is it blown? OK could be a relay or and this is a big or because 9 times out of ten its this, check a skinny black wire attached to something metal. These old cars slip their grounds all the time and you will spend a ton of money & time for no reason. If all the wires appear to be sound, go to the console area in between the seats. The wood veneer lifts when you remove 2 screws at the very front of the console storage box. Pull and lift. You should be able to see the roof/rear window swith along with the front window switch wiring. Check all the wiring and naturally the black ground wire. The wiring harness releases from the switch by pressing in the tabs on opposing corners. Clean up the switch and replug. Does it work? If not, go back to the convertible roof lift pump and switch around the relays. Anything? Chances are that is the other windows are working fine and there are no leaks and if the wiring is ground and secure AND if the switches are gunk free, that it is a relay. Do not buy one from these online greed mongers, you can get relays for 1 dollar each at any local sal

vage yard.
