Instrument lights, 93 '90 CSQ

[Diana Johnson]

Well, now that we've replaced the valve cover gaskets within the first
week of owning this car and it no longer leaks a drop (Yahoo!  No head
gasket leaks!), I can obsess about the smaller but nevertheless
irritating things that don't work right.  If anyone has experience with
the following, I would really appreciate your advice, especially since I
don't have a repair manual yet:

(1)  Light bulb behind the automatic climate control display is out.
The fan works fine, but the backlighting on the right side of the panel
is gone.

(2) Bulbs behind the driver's side seat heater button and the defroster
button are out, but both work fine (just not lit).  Anyone know if I
have to replace the whole switch on those or if there's a way to put in
a new bulb?

(3) Light bulb behind the outdoor temp. display on the same panel as the
tachometer and speedometer also out.

Piece by piece this is slowly turning into a new car!

Thanks,
Diana
