Confirmed two motors are OK, and manual operation of the roof opens and closes it easily.

I've about convinced myself I have inadequate amps arriving to the little DC gear motor to actuate. Will move about 100mm forward and then stops. IF manually cranked closed, it will OPEN about the same distance and freeze

No schematic can be found in section 371, even tho the 830 Power Sunroof section says that is where it resides.

I expect that possibly the main sunroof switch might have burnt up contacts, and/or a hidden relay (back seat?) might have the same issue. Contacts burnt = high resistance = low current.

If anyone knows where that schematic is hiding, please advise.
