Jaguar Repair: 1986 XJ6 III power windows stopped working, xj6 series, master switch

Question
We recently purchased a 1986 XJ6 series III. The car is in great condition. However, the other day all the windows (4) as well as the sunroof just stopped working. Where should I start in troubleshooting this problem. I find it odd that ALL of the windows stopped working? Any input appreciated.

Answer
Please buy a manual. I have answered this question before. Please check the window lift relay, window master switch and thermal breaker. Items 215,231 and 259 on main wiring diagram.Check to see if power is getting to the master switch, the center top switch on the console. I hope this helps.
