Cool, the bulb replacement is what I was looking for, the steering wheel (it
needs to come off on a 90) and instrument cluster are already strewn about
the garage so I can spend 2-3 hours putting it back together instead of 30
min ;).  The temp gauge is on the work bench. Off to Radio shack in the
morning.  Did you send this procedure to the knowledge base?

Thanks,

Tim

    Has anyone replaced the bulb in theirs? If so what did you use?

    Anyone interested in all that can be done with it and can also read

    I am always amazed what I can find on the web.  Thanks to all of those

    publish their trials and travails.

                                        OAT Bulb Replacement

                                        Robert Myers  <robert at s-cars.org>


  This requires minor surgery.

  1.      Adjust steering wheel toward vertical and as far from dash as
possible to allow more maneuvering room during the cluster removal.

  2.      Pull the instrument cluster. (10 minute or less job. - 2 or 3
screws removed from below the lower trim strip, slip out the lower trim
piece (there is a slip joint "post" on the right end - remove the screws and
slip the left end of the trim piece toward the rear of the car and then pull
it toward the driver's door).  Remove another 3-4 screws along the front
bottom of the cluster & slide the cluster out of the dash.  Disconnect
several color coded and keyed electrical connectors behind the cluster).

  3.      Remove the OAT display from the lower rear of the cluster.  (10
seconds - two small screws)

  4.      Disassemble the OAT display.  Take your time and put everything in
order as it comes out - nothing is marked.  Unsolder the grain of wheat
bulb.  Solder a replacement in its place.  (10 minutes)

  5.      Reassemble everything - aren't you glad all the bits and pieces
are arranged all nice and orderly?  (Another 20-30 minutes)

  The replacement bulb is available from Radio Shack in their display of
small lights.  I don't have the part number handy but it is their smallest
grain of wheat bulb.  It comes packaged two to a blister wrap package.
Somebody reported Radio Shack bulb # 7219 Micro Lamps 12 volts, 60mA.

  The only concern is just how comfortable you are with soldering itsy-bitsy
electrical gadgets.

  The behind the dash electrical connectors are locked with a variety of
methods.  Nothing requires brute force to get them apart.  Just look closely
at them and figure them out.  Nothing is terribly complex.
