2006 chevy impala overheating
Car overheating, ac stopped working not blowing air at
all. Fans only kick on when car is turned off. we have
replaced thermostat and water pump and raditor.
How hot does it get in degrees F? Some vehicles, if the computer thinks the engine is overheating/overloaded the computer will disable the ac compressor, that compressor is a load for the engine. Is there an air bleed valve for your cooling system? Did you try to bleed air? Some vehicles, if you unplug the coolant temp sensor, the fans will run all the time. If engine is overheating, the fan/s should be running. Any applicable trouble codes relating to coolant temp sensor or anything?
Sounds to me coolant sensor. My 2011 impala ltz has same issue. My problem is i can find it and don't want to unhooking stuff to make room to locate the sensor
