diagram or a video plz,ive got the passenger window not working and the

vsandvs says:

Update on roof controller: after replacing chips and some diodes controller
works after few restarts. I suspect either oscillating crystal or main
processor to be faulty. Could not find replacement crystal anywhere. Found
processor chip but cannot program it. Recently got my hands on not working
roof controller and will try to either fix that one or use crystal off that
controller.

Do you know if a micro switch in the soft top controls the release of the
tonneau cover over it? I had fixed a pair of severed wires on the left bow
extension cylinder, but still no change. Are there additional micro
switches under the soft top frame assembly? Also the control over the roll
bar only works when I have the hard top on and locked. I don’t have control
over it with the switch when it is off.

DaytonCarCare says:

Have you ever repaired the dome light circuit board? I replaced the relay
behind the passenger air bag and now my driver door light is working but
not the dome lights.

Good video. Thanks.

I have a 92 500SL, issues with soft top and hard top locking when I got the
car. The front power latches work for locking but not unlocking (I manually
unlock with allen wrench). The tonneau cover will not open to release the
soft top. After manually opening tonneau cover only rear window pivots for
the soft top. My door windows work no problem. Roll bar switch works, but
sometimes finicky after removing and re-installing hard top. Soft top
controller problem, or maybe micro switches??

Thanks for the Video. My soft top controller is bad. I will need to get it
pulled out and sent to you. I drive a 1993 300 CE CV. It became
intermittent then it finally just quit folding down. Great Vid.
