Q: I have a 2009 Chevy aveo. The temperature gauge is under C and the hold button is flashing. I have a/c and heat is working.

asked by on February 06, 2017

My 2009 chevy aveo has had a lot of work done to it last year. I have had work done on the transmission about 6x in just 3 months. I have a/c and heat. This has happened before where the temp gauge will be below C and the hold button will be flashing. I know the hold button has to do with the transmission.

My car has 90000 miles.
My car has an automatic transmission.

Hi there. When the temperature gauge displays below the "C" - this is typically an indication that either the coolant temperature sensor is damaged or the display gauge itself is faulty, has a blown fuse or there is a communication error from the sensor to the ECU. A broken coolant temperature sensor can cause hard staring issues (in colder weather) and overheating problems while the AC is active. You should probably have a professional mobile mechanic come to your location and complete a temperature gauge inspection.
