Hello,

After 5 years of dealing with non functional rear windows on my 1985 300TD, I decided to tackle the project. I found some less bent rear regulators at a salvage yard, and straightened them and installed them in the car.

Here is the issue, I am not getting any power to the drivers side rear door switch. The window motor is tested and works, and I tested the pins and I am not getting 12 volts. I swapped the master switch with a spare, and it did not change.

I am not getting power to the black/pink (#3) wire like the passenger side. I may have shorted the wiring when I took the regulator out, as you have to dismantle the switch connector to removed the window motor. I did have the negative battery cable unplugged, but I had to move the car because of street sweeping, and I forgot to tape the loose connections. They may have touched when I moved the car.

Feeling a bit frustrated, hoping someone could help narrow this down. Thanks for your help.
