Seat Heater Q

[Steve Sherman]

My recently  new to me 91 20v has a dead drivers side seat heater.  The
lite in its dash switch does not even come on.  Now that our local
weather is cold in the AM but hot later in the day, a seat heater would
be nice,; so I thought I would look into it.  I did not see any signs of
blown fuses.  but did not know the right way to pull the switch from the
dash.  Can these switches be pryed out without screwing things up, or
does one need to remove screws or latches in the back?

Any common failures suggested byt a seat heater switch whose lite does
not come on?

TIA
