CLA250 Cooling Issue
My sons 2014 CLA 250 just had the Thermostat changed. The car operates at the correct Temperature but after the car was driven about a thousand miles when the heater is turned on the engine temperature immediately starts cooling down. He is out of state which he just had the computer checked. The car had a Y133 code and a B11-4 code. Does anyone know why the car would cool down when the heater turned on?
