Tunatic, Personally I would agree to check for a short to ground in the circuit. However, verify the sending unit first, it cost less than $20 and can be replace easily.
Good luck and let me know if you need anymore assistance.
Best regards,

If the gauge is stuck on cold the temp sender wire may not be connected. If it is stuck all the way hot the wire could be shorted to ground. If the wire is not shorted to ground and the needle is all the way hot you will have to buy an instrument cluster because they don't sell individual gauges. You can buy a remanufactured instrument cluster. They run anywhere from about $300.00 to $425.00. Hope this is helpfull.

    Now with the key on ground the wire from the sending unit and the gauge should go all the way hot.

I have a 2008 Chevy Colorado and today my temp


when a temp gauge drops to cold ,it indicates a problem in the cooling system
temp gauge sender units need water to activate the resistance that makes the gauge read so a falling gauge indicates no water around the sender unit --- air lock in the system--faulty wire connection to the gauge sender unit
the ac unit is not connected to the temp gauge so there may be another separate problem there
the temp sensor is an entirely different unit to the temp gauge sender unit and the short term working would be from an altered coolant level from changing that sensor --air lock in system
the temp sensor connects to the ECM to activate the fans and monitor engine operating temp so as to keep the air/fuel mixture exact for the engine conditions
the temp sender unit just makes the temp gauge read
a faulty thermostat will either be stuck open and the engine temp will take a long time to rise or it will be stuck closed and that will cause an overheat very quickly

My chevy van 1500 express cargo has the temperature gauge stuck at 0.everything else works fine


If the engine is reaching normal temp, you would need to test the sensor on the intake and the gauge on the dash.
The sensor provides ground to the gauge.

2003 chevy silverado, fuel gauge started registere...


Common problem on the 03-06 Silverado instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Silverado fuel gauge problems

Temperature gauge red lined then dropped back down


more than likely but if the temp gets to high you run an extremely high risk of blowing a head gasket or warping or cracking the head.So have it changed out before driving the car much more and also have the water pump checked.

there is one fuse for all the dash gauges, so chances are you have a wiring problem to the gauge sender on the engine or the gauge is defective, which is rare.

Problem with No Heat on 2005 Chevy Avalanche - Cooling System?


it is most likey a sticking thermostat it either gets stuck closed or open in your case closed so collant isnt getting to the heater core and all you get is cold air blowing into the truck.
its a simple fix you can either do it your self or take it to a mechanic. now remember there are differnt thermostes so think about the climat you live in and get one according to that
