A huge thank you needs to go out to 77CVT for supplying me with 54 wiring diagrams for my 84. I think I have been able to track down the problem to my wiper switch. In saying this, it has now led to a mini project. While the door trim is off I may as well do all the othert work I had planned to do later, with regard to the doors.
Replace the Inner Window Seals, change the colour of the door trim, replace the rubbers, replace side mirrors with ones that are electric (which need painting first), check why windows take so long to move, correct left hand side window from rattling and place some insulation into the doors. Just to keep the music inside the car....
Once again thank you 77CVT.
