I have a 1996 chevy caprice my
temperature hand doesn't work and I
changed the temperature sending unit wat
else could be the problem?
The guage it self or the wire going to it from sensor.
Unplug the sending unit and with the ignition in the run position ground the wire by touching it to something metal that's not painted. The gauge should go to hot. If not either the gauge on the dash is bad, the wire has a break in it, or the printed circuit on the back of the instrument cluster is bad. If the gauge goes to hot you have a defective sending unit. When replacing the sending unit do not use any sealant on the threads. HTH. -Jim
Try the other hand.
