A lil prob with my windows...
 

I have a problem with my rear windows on my 1987 420SEL. When I bought the car, they worked excellent. All of a sudden, they dont open from the back anymore. The motors are excellent and they only open from the front master controls. What is the prob?? I replace the switches already in the rear and still I cant open them from the rear. I also checked the fuses and they are good. Also, one of my rear windows gets stuck sometimes when I open them?? WHY??? It would take me forever to close it!!!

By chance, is the child lock for the back windows in the lock mode?

The child lock is not in the"LOCK" position. No matter where that button is, they still dont open from the back
