[s-cars] Sunroof Stuck Open - Update

[James Murray (QA/EMC)]

Bob, still sounds like the switch to me... if you remove it you will see
that the switch can be seperated, but take extreme caution... the tabs on
the side break easily. Once opened you will see 3 prongs, basically it's a
large potentiometer... clean the contact up and while your at it resolder
the connections from the wires if they look suspect. The position of the
prongs on surface of the resistance dictates the position the sun roof
should be in or the travel of the motor... that's why sometimes you can get
"ghosts in the machine" if the prongs loose contact (i.e. sun roof opening
by itself).

Okay, with ignition off and switch in closed position, I cranked the
roof closed manually (BTW - don't forget to pull out the red locking
plug first.  Wasn't intuitively obvious, to me at least.).

Sunroof now retracts and tilts properly, except if I retract it all the
way.  The sunshade goes back and pulls forward as it should.

If I turn the rotary switch to full rearward position the roof will
retract all the way back and get stuck.  Essentially what is happening
is it is going beyond the normal travel because the front edge of the
roof panel is now flush with the back edge of the opening in the
headliner.  Typically about an inch or two of the panel would still
show. If I turn the switch to one click before full stop the roof stops
at it's proper position.  Turn it that one extra click and it
overtravels.  Busted switch?  It doesn't appear as the mechanical part
of the roof is faulty, just that it's getting a command to go too far.

Bob
