Many thanks for the quick response.
The Gremlins are biting hard.
Luckily I have speakers in the door cards. Took the speakers out and took a good hold of that wiring
Tested the earth - tested the voltage going to the windows. all good :-0
Then run a line from the + on the battery directly to the window motor and "WHAT" it works??
Connected all the wiring back up and ...... It worked like nothing was ever wrong?
At least its working and all polished up ready for the show.
