Hello everyone, Im fairly new to this forum and I have a 1987 300D All my windows work save for the drivers side rear, I took the door panel off, thinking it was gonna need a window motor replace, but when i tested the motor with 12V. I tested fine, I tried swapping the switch in the console with an other one I got from a friend and same result. I took a light tester to the wires leading to the switch in the rear door and wasn't able to read any power going to it when the switch was in use. The rear pass. window works fine.

Has anyone else had this problem or does anyone have any suggestions?
Thanks in advance for any and all help.
