Dave,I would recommend the installation of relays for the windows.If you would check the voltage at the supply wires at the connection for the window motors you will probably find there is considerable drop in voltage. The motors do not work well at anything below 12.1 volts. I have fought this problem for 40 year before I installed the 4 relays.

The right side power window goes down but sometimes doesn’t want to come up.  When I reseat the wiring to the switch it works fine until I disrupt the wires again.  I was playing around with the wires to the radio and at one time I had everything working fine.  Then I tried to put everything back and went back to the same issue with the headlights I had before.  I suspect it is related, but only one since I’ve had the car (about 6 weeks) has the red ignition light ever come on when I turned the key on and that was when the headlights were working as they should.  The map light has always worked when either door is opened.

David,
 
This is a tad radical, but on all the Marcos cars that I have worked on, I have removed the thin plywood dash top to gain access to the workings below,
 
The removal is simple, however you will need to use that piece to as a pattern to cut a new panel. Then, I attach the new top with #6 x 1/2" screws for easy removal the next time I need to have access to all that wiring, heater core, wiper motor and drive tubes..
 
As I remember, there are a bundle of ground wires with ring terminal that have a bolt and nut securing them, but not fastened to the chassis at that point.
 
An other point you might want to check would be the connections in the map light at the top of the center panel between the headrests.
 
Do your power windows work well?
 

Regards,
Larry

The wiper motor is behind the glove box.
 
I do not think that is where you need to go unless you have a problem with the wiper motor.

I’m still looking for a possible ground issue. Joe Cubitt says there is a ground post behind the dash near the wiper motor.  When I remove the top of the dash, I don’t see anything that resembles a wiper motor or a ground post.  What do I need to dismantle to get to this grounding post?
