Window regulator - adjusting door glass

[onZedge]

I had the door card off to repair the door handle - broken casting in the handle where the "reverse lever" attaches - more on this in another thread.

While I had the door card off, I decided to investigate why, with my window cracked an inch or so, it sounded like the window was about to fall out of the car when I closed the door. My window looked a little high in the back and low in the front, so the window glass was not square in the window channel. The low front appeared to be the cause of most of the noise. I searched everywhere (Clarks, PP, RL, YT, 924org, FSM, PCNA) and could not find instructions for window glass adjustment, and didn't really find anything useful, so I thought I would share how I made the adjustment.

I spent a little time studying how the regulator works and realized the three screws around the motor (2 over, 1 under) hold the regulator assembly to the inner door skin. The two rearward screws (circled in the photo below) are for window glass adjustment. With the window down about 4-6 inches, I loosened those two screws and observed what the window glass did when I moved the screws up and down in their vertical slots, both individually and together. I ended up with the rear screw down in the slot, and the forward screw up in the slot (your results may vary). This lifted the very front of the window and squared the rear of the window glass in the window channel. Now the door sounds solid, with the window in any position, when you close the door.

I forgot to snap a pick before I put the door card back on, so credit for this photo is from JohnJ's 924S Restoration thread (same car and color as mine).



I hope someone finds this useful!

Thank you! That is useful.

There is a good write up in the shop manual about how to adjust the regulators.

I have the bootleg copy of the FSM that has been floating around the 'net for decades. I did not find a write-up in the copy I have (which is not 100% complete), but maybe I didn't look hard enough.

In which FSM subsection and page does the regulator adjustment appear?

I recently fought with a slow one, the rubber seemed to be causing too much friction so I sprayed the guide chanel with silicone , like pam spray, not tub and sink sealant ;-) it worked.

I tend to hide that stuff from myself to prevent overuse,

it will wreak havoc upon any future paintwork you plan to do.

I wasn't aware of those adjustments, this is very useful. Thanks!

When I have had window problems I have usually just cleaned and lubricated the track with grease, which helps a lot but the window still raises unevenly.

The adjustment you describe may compensate for some wear in the regulator.

Great post!
