1995 XJS, 6. L V-12, 64000 miles

So the weather is finally warm and dry enough to take her out of hibernation. Washed her nice, put the top down to make cleaning inside easier.

The driver side window will not go down, won't budge at all. It was open maybe an inch or so and I put it up to wash the car. Passenger side works fine, and the small windows behind the door retract, as does the convertible top. I hear absolutely nothing when I press the window switch.

I'm going to examine the fuse first, but any suggestions on diagnostics would be appreciated. It'd be nice just to get the window down for her first ride of the season.

Thanks in advance for any insight.

 

One update: I can hear the window motor engage if I press the up-direction, but nothing on the down-direction. Maybe the switch? Can I jumper a few pins in the connector to see if the window will go down?

 

Here's the schematic. Not much to it.

 

Easy-peasy!! Thanks petemohr.

 

Strip all 3 switches down and clean them. You will be amazed at the muck inside.
