All of the guages work on my dash except the temp. When I first start the
truck the guage needle actually moves to the left but as the engine heats
up it never moves into the normal range. The fact that the guage moves to
the left I would think tells us that it is working but am not sure what the
BTW once warmed up the heat works very well.
Any help would be appreciated.
Sounds like either you got:
broken wire going to the sending unit
or it came disconnected
or a bad sending unit
The best test I know of is to unplug the wire from the sending unit and touch it to ground, this should peg the gauge to hot. If so your gauge and wire is fine and you have a bad sending unit. If there is no movement the you have a bad wire or gauge.
