No ur AC should still work it may just be that your gauge is jammed and just needs to be loosened take it to the nearest garage as you dont want any overheating of the car or it will costs you $$$
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.
A faulty temperature sensor, a wiring issue, or a blown fuse could cause a temperature gauge to stop working. It could also be due to a malfunction in the gauge itself.
check the wiring, and also the sending unit, and also check the gauge to make sure its working properly.
An automobile temperature gauge can fluctuate when the thermostat is opening and closing erratically. The temperature gauge can also fluctuate when the ground wire is loose.
Check all your wiring connections, it sounds like you have a loose connection somewhere, also check the harness plugs and make sure they are also tight.
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
If the water temperature gauge on a 1992 Ford F-150 is not working despite having replaced the sending unit, the issue could be due to a faulty gauge itself or a wiring problem. Check for any damaged or corroded wires connecting the sending unit to the gauge. Additionally, ensure that the new sending unit is compatible and properly installed. A blown fuse in the gauge circuit may also be a potential cause.
When the gas gauge stops working in a vehicle, the first thing to check is the fuse. This is an easy and inexpensive task and may end the problem right then and there. If that isn't the issue, there could be a lose or broken wire between the gauge and the battery, or the float could be stuck or need to be replaced. It is also possible that the voltage regulator is failing.
Have you checked for leaks? also the cooling fan may not be working.
A non-functioning temperature gauge in a 2005 GMC Yukon Denali could be due to several reasons, including a faulty temperature sending unit, a malfunctioning gauge itself, or issues with the wiring or connections in the dashboard. Additionally, a blown fuse or a problem with the vehicle's engine control module (ECM) might also cause the gauge to fail. It's advisable to perform a diagnostic check to pinpoint the exact cause for accurate repairs.
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
If the temperature gauge in an S40 isn't working, it could be due to a faulty temperature sensor, a broken wiring connection, or an issue with the gauge itself. Additionally, low coolant levels or a malfunctioning thermostat may also impact the gauge's function. Checking the sensor and wiring for damage or corrosion, as well as ensuring the cooling system is functioning properly, can help diagnose the problem. If these components are in good condition, the issue may lie within the instrument cluster itself.
