92' GMC thermostat problems
#2
The sensor for the gauge is on the drivers side of the block and has a single wire going to it. Make sure it is plugged in and if so, try grounding the wire to see if it makes the gauge move. If it still doesn't move than the guage itself is bad or you have a broken spot in the wire somewhere.

mhmmm. Me and my Dad took a look under the hood and there is one wire not plugged into anything. When I change the air filter tomorrow I'll post some pics.
Correction, heat gauge not thermostat
