That is the way it is supposed to be. It makes it easier to implement a two-switch system such as is used on the rear windows. So they use it everywhere for consistency. I don't know if the motor is toast or not. It may just be the brushes. but they are difficult to change, (I know from personal experience) so a (possibly junkyard) replacement is probably in your future. The motors on my 81 TD are all still original so these are generally sturdy items. The brushes and bearings are the wear items and the brushes are by far the more likely item to go first. But you will have to try to turn it manually in order to test the bearings. either way the motor will have to come out.

Been a while since I had an issue to come here with. now I have two.
1. The driver window will not go up or down. I removes the door panel. Checked for voltage. Both the green and black wire have approx. 12.4 volts with key on. Hit the up button, voltage drops to 0. Hit the down button, voltage drops to 0 in the other wire. Is this the way it is supposed to be. If so, is the motor toast. What do I do next? Seems backwards to me. I thought the wire would have no volts till switch is pushed then would go up to 12 volts.
2. Glove box latch is not working properly. Is there a repair kit for these? Do not like using the bungie cord. Looks kind of trashy.
Any help would be great.
thanks, Nick
