The inside roof panel has plastic guides that sometimes break. I replaced a
set of them on my daughter's car, but now the glass roof panel does not stop
in the right place.
I removed 6 screws to take the glass out, and put the screws back in to hold
the glass. I do not recall the holes as having slots in them, so I didn't
bother to check that there was an adjustment point there.
If I monkey with the switch that drives the roof, I can force the roof to
park in the right place, but if I simply use the roof switch as it is
designed, the glass sits too low in the hole. The result is that there are
air leaks now, and my kid says that water comes in while she takes the car
through the wash rack.
I haven't got a manual for this car, so I have to do a certain amount of
flying by the seat of my pants. Is there a specific adjustment for this
area, or is the proper procedure to just take it apart until it works?
