W140 Coupe
 

I just posted this on another forum, just wondering if any knows:

I tried to get my windows tinted, had my dad drop the car off to his friends (USATinting). They tried to make the window go all the way up when the door is open (its normally not because it "reseals" itself when you close the door), now I can't get the passenger side and the rear passenger to go all the way up and seal via one touch....help please!!!

Also, my head unit is doomed! When ever I adjust the volume, it doesn't want to cooperate and or it will do the opposite: turn it up, it lowers; turn it down, it goes up....Arrrrrrgghhh!!!

A quick guess is that they disconnected the battery and then forced the door open over the seals in order to keep the window in the "up" position...
If so, you'll need to reprogram the windows. Run each down all the way and hold the button there for about 10 seconds. Make sure you push the button all the way down. That should reprogram your windows.
Your radio issue is a dead volume control... needs to be replaced.
Hope this helps.
