I've been restoring my 59 Bird and doing pretty good...recently replaced door and window seals and started in on power windows..went thru switch contacts, mtrs etc...got 2 rear and pass side working great..driver side mtr good, but would not run with switch...used batt. cables and it ran great..found that the black wire is not grounded for some reason..works on the other 3,,,I ran a temp ground wire from the black lead to ground and the it works like a charm..the two rear circuit breakers are mounted to the floorboard under the rear seat to ground and the 2 on the engine firewall are grounded..so what could be the problem with the driver side door window black wire not being grounded ?? also my dome light is staying on no matter if doors are closed or open..both door switches are good....a short somewhere and could this be the problem with the black window mtr black wire not being grounded ?? appreciate any help..
