Does the gauge do its normal sweep test?
Cna you provide me details aboout the sweep test?
when you turn the key on the gauges go full on then off then up the readins .
I haven't noticed that, give a second.
apparently the gauges don't go to full, any of them, they go directly to normal reading.
OK, do you get any warnings then about the heat?
Does the heater work gine?
sorry , fine?
Yes, it works, In fact the warning message "engine service soon" is on always, I have to get the car scanned. Cna this fault be related with other sensor besides the ccolant?
Honestly this is sounding more like a stuck thermostat all the time. have you changed that?
Yes, it is new, we have tried replacing most of teh cooling system components,(water pump, radiator, coolant temp sensor, thermostat). As today the temp is "controlled" but at higher temp as it supposed to be
Then all that is left is the gauge itself is faiing.
Do you have an estimate of how much is the cost to replace it? How can I make a search for it?
most places repair them for about 100.
those are online places not a dealer.
Have you seen this kind of fail before?
yes it is common on GM clusters.
that is why there are hundreds of places online that rebuild these.
"Who" controls the on/off of the radiator fans, the coolant temp sensor, the gauge, the car computer...?
Powertrain Control Module
