FW: Temp gauge on 1994 90S

[Teri & Jeff]

First, I would run the diagnostic tests on the instrument
cluster.  This drives the gauge to the normal position ("the
first fat mark"), checking the gauge.  Then I would check the
manual for the proper resistance of the sender and check it with
an ohmmeter to see if it's within specs.

If the gauge and sender check out as working correctly then I
would suspect a thermostat that is stuck open.
