Temperature gauge is blank, fans are on full blast, warning to turn off A/C

Asked by Christina Aug 03, 2021 at 11:18 AM about the 2013 Chevrolet Camaro 1LS Coupe RWD

Question type: Maintenance & Repair


I have a 2013 3.6 V6. Last night in 75 degree weather
after my car was parked all day. I start my car to go
home and about 15 min the temp gauge doesn’t
move and the digital reading is blank. No temp at all!!!
Car says turn off A/C to avoid over heating. Fans are
all on full blast.

I stopped and checked coolant and it’s full. A/C once
turned on is HOT. No leaks or puddles under the car.

I’m thinking thermostat is stuck.
No codes will pop up cause check engine never
came on.

Sounds like a bad coolant temperature sensor or a bad connection for the coolant temperature sensor. When the computer stops getting a signal from the coolant temperature sensor it assumes that the engine is overheating and takes precautions to prevent engine damage. Such as disabling the air conditioning. Hope that helps! Jim
