hey there...i have an 85 300td wagon...the front driver side window is inoperable...i tried replacing the switch...no change...the motor in the door makes the usual noise when i use the switch but the window doesn't move...i am assuming it is the regulator...could it be the regulator AND the motor???...any wisdom is appreciated...
Most likely failed regulator
If you can hear the motor run it is most likely a failed regulator. We have some good used ones in stock. If you need help in removing and replacing check out my 123 Chassis Door Maintenance and Repair Manual.
