Window Regulators
 

I have a 1978 300 D Turbo Diesel & only the Driver Side Windows will go up or
down.
Where should i Start Looking.?????

the only way
 

to diagnose these is to take off the door panel. be careful cause some of the fasteners are a little trickey to find.

it could be the regulator, or just the wheel on the end, or the motor. or it could just be stuck and need cleaning. the little wheel is pretty cheap and easy enough to change. course cleaning it and putting it back together is the cheapest... after finding a blown fuse.

actually a blown fuse would result in the rf an lr window not working and vice versa.
