Recently purchased 1986 vanden plas. Had bad alternator and battery, replaced both. Now non of the four windows or sunroof work, all fuses are good. Any ideas? The master switch on console only flips from top to center, looks like it should also flip down?

 

The master lock-out is only two position. It's function is to make/break the ground path to the power window relay.

Assuming the lock out switch isn't faulty the relay is the most likely culprit given the scenario described. If you have a test meter or test light there are some easy checks to make.

The relay is at the extreme right end of the dashboard, outboard of the right side of the glove box. It's a generic 4-pin accessory realy with the usual 30/85/86/87 terminal designations.

Thank you! Have been searching internet and haynes manual trying to find relay. Changed it today, problem solved.

 

Good work :-)

Might wanna get the actual Jag manuals and wiring diagrams to replace your Haynes.
