The electric/power sunroof on my '85 golf only opens a fraction of an
inch at a time.  Each time I press the button it opens something like
half an inch.  There's a distinctly audible click, like an electrical
relay opening.  I have to release the button and then depress it again
dozens of times to get the sunroof fully open or fully closed.

Does it just need to be lubricated?  Or might it be an electrical
problem?  What kind of lubricant is recommended for this year/model?

As a side note: Removing the plastic panel covering the sunroof motor,
I was amused to find that VW has stashed an allen wrench right there
for use in manually opening/closing the sunroof.  I don't know whether
to praise them for their clever foresight, or chastise them for
shipping a known failure-prone system!

thanks,
Tobin
