You don't want to hear this, John --

1) live with it
2) swap out your temp gauge
3) drill out the rivets holding the face on the gauge and remove
face.  Desolder circuit board from the two posts, carefully removing the
coil wire from the right-hand post first.  Desolder the +10v wire from the
board.  Remove the 10 uF electrolytic cap and replace it with a good one,
preferably tantalum.  Observe polarity -- there's a + mark on the
board.  If possible test with +10v and ground after removing cap -- light
should not light.  Wipe a damp finger across the pads where the cap goes --
light should blink until you dry it.  Touch replacement cap across pads --
light should blink then go out. Put it all back together after thoroughly
cleaning the circuit board with circuit cleaner.  While you're in there,
replace the LED with a brighter one, you'll never have a better chance.
