Question about 2004 Chevrolet Cavalier

5 Answers

I have a 2004 Chevy Cavalier, none of my gauges work. It started with the temperature gauge (we replaced the sensor but it didn't change anything). The temp. gauge dropped all the way to the right. Now the fuel, speedometer and rpm gauges are not working.

    Mine does it too! Started with the speedometer (going about 50mph reads 25), gas gauge once, tachometer once. Now the speedometer does it all the time. It keeps fixing itself though. Anyone know an east way to fix it?

    I'm having the same problems--no dash instruments work--I was going to try some fuses but it looks like there is something else going on here that will eventually effect the performance of the engine. I have no warranty and don't know of a trusting mechanic. Any suggestions where to start?

Bad Stepper motors....the motors in your cluster are very weak... there is an upgraded motor x 25-168...cost 175.00 parts and labor to replace all of them. Ive repaired a lot of clusters with this very problem

These cars have bad instrument clusters with small motors to work the gauges. Install a replacement cluster and it will fix the problem

There could be a earth come off to the clocks or a loose wire shorting wich caused the temp gauge to do that.

Inherited the 2004 chevy cav. in JUne. ABS Trac and other lights on and off. finally drove it across the US and the shifting started to go and this would include the speedometer would just crash and do nothing.. After numerous trips to the dealer and others to test it. finally a dealer found the problem and replace d the computer (said under warranty, we don't have a warrantly but it must be a factory fix up one), anyway, have yet to pick it up but this had been ongoing for months and hope that you all dont end up like us. HInt, ours would only do it once it got hot. live in 100+ temps but would run car alot to get it to show there is a problem when we got tested last time. Maybe it is all tied in. only thing I an think of that would mess up your speedometer. good luck.

Why does the temperature gauge on my 1995 Chevy K2500, 5.7L read 150 degrees ?


If you replaced the SENSOR and not the gauge SENDER, there's your answer.

The SENSOR sends the computer (ECM, PCM, ECU, etc.) the engine temp so it can make the adjustments to the fuel, timing etc.

The gauge SENDER makes the gauge read what temperature the engine coolant is.

Hope the helps.

There are two possible candidates here, both of which you claim to have "checked" as good. They are the ECT (Coolant Sensor) or the thermostat. As the gauge works "occasionally and when it does fuel mileage is much improved", I would take the cheap route and change the T-stat and see what happens. If the thermostat is intermittent sticking in a wide open condition, this will result in the inability of the engine to regulate its coolant temperature. Engines run more efficiently at higher block temps because it aids in the combustion process. Many DIYers often change out 180 degree thermostats for 195 degree ones because they see marked improvement in power and fuel mileage. The ECT samples the temperature of the coolant and sends a signal to the PCM. The PCM uses that to determine rate of fuel delivery and also sends the signal to the temperature gauge on the instrument panel. A cooler engine needs more fuel, thus the decrease in gas mileage. You don't mention anything about the vehicle running rough, so I'm assuming that the ECT has it right. If the ECT were faulty and the engine were warmer than the ECT says, you would probably start having running issues since the engine would be running too rich, and that could possible even set error codes and the Check Engine Light.

Well you've lost power to one or two major circuits. Could be a problem with the key switch or a major fuse in the engine compartment.
I would check the fuses for power and find out which ones are dead then go from there.

My 1992 Chevy cavalier used to run at 1/4 temperature gauge, started running super hot so I replaced the water pump... Now it stays at 1/2 temperature gauge steady. Why? Also, how does electric fan work?...


I'm not sure about the electric fan relay or fuse are but you may want to have your radiator flushed. It's possible that some of the tubes in it are plugged up and so your cooling efficiency could be low.

So I have a 2001 Chevy cavalier and I just hot it back from having the fuel pump replaced and now none of the gages work is there anything I can do to fix it


There is some sensors that they had to disconnect and other wires that they most likely removed to install fuel pump such as sensor that monitors fuel pump preside. Trace any and all line to the fuel pump to see if were hooked up, if so unplug and plug back in, possible not good connection. Let me know results. Thanks mike

My 2004 chevy cavalier temp gauge goes to the middle as soon as i turn the car on and then to heat it's not overheating i got the cooling flush and the radiator serviced and replaed the thermastat what...


It could be a simple as a coolant temperature sender. I'm not sure where yours is located on your car but alot of Chevrolets have two of them. One for the gauge and one for the ecm. If you know where it is just turn your key on and let your gauge do its thing and then unplug the temp sender. If your gauge pegs out or drops to zero that is probably your problem if it is reading in the middle and the engine is cold. You could have a problem with the gauge as well but start with sender.

If my 2004 Cavalier sits overnight and the temp gauge stays at 3/4 fo the way to hot, could it be the gauge or something else


More than likely it's the gauge but you don't say if it ever goes all the way down or all the way to hot. You don't say if the engine actually ever over heats, ie: loses water, steams, dies or anything like that. If the engine never actually overheats more than likely it's either the gauge or the sensor. You've got a 50/50 shot but I would put my money on a faulty gauge.

2004 chevy cavalier temperature gauge is all over the place, engeis not overheating, seemsto be running fine


Check your coolant level. If you have air in the lines, the times when there's no coolant in the area of the sensor will make the temp go up rapidly, then it goes back down when coolant hits it again. You need to get the air out of the system, or you WILL have larger issues at hand, like a blown head gasket, cracked head, reduced piston ring sealing, or material transfer from the pistons to the cylinder walls. One other thing that could cause this is a faulty thermostat.
