[Shotimes] Moonroof relay stops motor at wrong spot...

[Chris "Zap"]

    I'm currently attempting to fix some of the weird problems on the '91 
PLUS that we just got, and the one thing that is leaving me confused is why 
the moonroof relay is operating at the wrong time.  It clicks to stop the 
motor just before the glass is all the way back when opening, vs the 
standard time when the roof is closed.

    Has anyone seen this problem before, or is there a known fix to adjust 
the stopping point?

Thanks,
Chris
