Hello folks,

Yesterday I noticed, again, that my temp gauge has stopped working. Last time
it happened it revived by itself when the car was next driven.  This time its
still dead.  Is this a common failure mode on the '89-100Q?  Is there a
connector corrosion problem at the sensor?  Where is the sensor located?
I'm about to leave on an extended trip and would like a functioning gauge,
so any tips/tricks/hints appreciated...
