First try unplugging the coolant temp. sending unit and plugging it back in(may just be bad connection at the plug), next replace the temp. sending unit if the plug-in thing didn't work.
It is possible that the temperature gauge has stopped working in a 1992 Tempo due to a blown fuse. It is also possible that the temperature gauge stopped working do to the temperature sensor in the engine having a short.
First check the fuse for the 2003 Cavalier gauge. Next check the fuel sending unit in the fuel tank to insure that its working properly. Check the gauge next, then the wiring for the system. One of these units is causing your gauge to not work.
Temperature gauge not moved and the fan's always are working
1990 Chevrolet Lumina temperature sender is located on the back side of the thermostat housing. The sender has a wire that goes to the temperature gauge.
If the temperature gauge is not working, one thing it could be besides the gauge itself is a blown fuse. Another possibility is a loose or broken wire on the gauge.Ê
The fuel sending unit for the fuel gauge would be located in the fuel tank.
If the fuel gauge isn't working on a 1999 Chevrolet Blazer it could possibly be because the float is stuck in the fuel tank. I had this problem when I got my 99 blazer, the float and sensor for the fuel gauge is on the fuel pump which is in the fuel tank to keep it temperature regulated. I had to replace my fuel pump, which ended up going bad on me, and after it was replaced the gauge works just fine.
Low Coolant? Weak Temerature sensor? Weak gauge Gauge working properly and recording the thermostat opening and closing as engine temperature fluctuates
If your temperature gauge isn't working the problem is a bad gauge, grounded or disconnected wiring or, most likely, the temp sender isn't working.
=A Gage is gun a 12 gage=
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
Hi, The 'easiest' way to see if the gauge AND sensor for the temperature gauge is or should be working is to connect a scan tool to the van that can read and display the information that the computer is receiving about the coolant temperature. Very often, there are conditions where the temperature gauge will read at its minimum value, but the actual temperature is higher. This is because the computer actually controls the gauge, and will set the gauge to its lowest value if it thinks the engine temperature is not rising fast enough. If you have a multimeter, you can also test the resistance of the sensor (located near the thermostat housing). The value should change as the temperature changes. Again, if that sensor is working but the gauge is not moving, more troubleshooting is required to find the cause of this issue. I have included a link that shows the location of the sensor (look at the bottom pictures). Good Luck, Greg
