Hi -

I am considering the purchase of a '96 Volvo 850 as a second car.  There
are two problems with the car that I know of:

a) The antenna mast doesn't move, but I hear the motor when the radio
  is turned on or off.  So I think the nylon chain must be broken
  inside.  I'm looking for instructions on how to replace the mast,
  especially the broken nylon chain.

b) The thermostat needs to be replaced (probably within the next year).
  I'd like instructions on replacing that too.

Thanks,
AC
