I wish you could have shown us the mirror operating.

Well I didn't show that because I think everyone knows how the mirror operates it goes up down left and right. 80% of the time when they're not working it's the switch. However sometimes you have to disassemble your mirror and check the worm gears or the motors

Hey
What can be the issue?
I adjusted my pressure on 2.9 bar on my transmission vacuum modulator (green one on gearbox). When small black cap is off then it hold vacuum, but when i put cap back on modulator then it losing all vacuum pressure.
My car is W123 300 turbodiesel 1984 with 722.315 transmission.
What the problem?
Thanks

You have a vacuum leak. You need to find the vacuum leak in the system or replace your modulator.

@@woodsandbarclay black transmission line holds vacuum perfect.
I connect banjo bolt with manometer on left side where is green modulator. When car is on idle then it lose all vacuum.

I just tried with handvacuumpump direct on green modulator and it’s holds vakuum perfect (car is off)
