several issues

[Mark Trank <mtrank%acva@mail.co.albemarle.va.us>]

Three issues:

1) My 5k has a nonfunctional temperature gauge.  Other gauges appear to 
be functioning OK. Is this likely to be a contact problem, a switch 
problem, or none of the above?

2) Sunroof worked fine for the first couple of weeks.  Now, it works in 
one position only (rear angle) but does not slide open, as it appears to 
be jammed.  Anybody encounter this before, and what's the best way to 
attack it?

3) interior door and overhead lights don't work.  Does one (or more) 
switch(es) control this?  

Anybody BTDT as to the above?

Collective thoughts and wisdom are, as always, appreciated.
  
TIA, 
Mark
