w108 window help?

Hello all.

I have a 1973 280se that I recently picked up. It's a generally clean car, but like most cars this age, there are a lot of things on my to-do list! But the most pressing matter at the moment is my driver's side window is non-operational. The center console mounted buttons were all snapped off, so I bought some new switches hoping the regulator/motor would still be functional (wishful thinking), but alas they are not. Anyways, to get to the point, is there a way to manually raise the windows for now so that I may keep the elements out of my already deteriorating interior? This towel taped to the door is not going to cut it for much longer.

Thanks in advance!

Andrew

When I adjusted mine because they were off over the years of usage I got all out except the motor
Shorter than removing the bolts as removed on the picture below and lifting the window up the next I can think of is removing the motor

Check fuses and make sure the seiches are clean, for example if the console switch is not plugged on the rear window switch will not work
It's all one circuit start checking

The window motors are monsters so I doubt it's the motor

Thanks for the quick response and for the pictures as well. I will check it out as soon as I get home from work. But in case the problems isn't easily found, any idea about manually getting the window up?

Is it just the one motor? All of them?

To clarify, I have the center console window switches in my car. The driver's side switch was missing the buttons and the passenger's side switch had only the front window button (and that window was functional, which led to my wishful thinking for the other windows)

So when I installed all new switches (refurbished), the front passenger continued to work and then the rear driver's side started to work as well. But the front driver and rear passenger windows still don't work.

I only pulled the panel on the drivers door to see if I could manually pull the window up, but I didn't want to break anything. And I realized a PO had attempted work as the moisture barrier was missing and there was one bolt (that holds the glass) missing as well.

I purchased a multimeter to check for power, but to be honest Im not positive on how to use it hahah. So I'll be looking all that stuff up today.

So THAT is why people say use the search function (well, I didn't search but rather went deeper into the vintage forums). I got from another thread that the two non-operational windows that I mention are actually on one circuit while the two operational windows are on another. I also got from yet ANOTHER thread that w108's typically have two 16a fuses for the operation of electric windows. (FINGERS CROSSED THAT A SIMPLE FUSE REPLACEMENT FIXES MY ISSUE)

Yep! The relays are located in the engine compartment, on the firewall, passenger side

a window fuse does 2 windows , in your case right rear and left front , so , if right rear work , it is not a fuse . the way to easily test , turn ignition on , now look at red light in cluster , and see if light dim slightly when using switch , if it does , the motor is getting power , but wont move .do it in up and down position .

I appreciate the tip. But in fact, my FL and RR windows are both non-operational at the moment. I just received some fuses along with a few other basic maintenance items from Peach Parts at my store. Now I can't wait to get home and try it out.

Thanks again for the tips everyone. (Fingers still crossed haha)
