Flashing AC\Heater control.
Hey guys, my AC\Heater control flashes for a few sec. after I start my car. Most of the time AC works good but last night my heater came on instead. Tried to adjust temp but heater still ran warm. Checked water in radiator & overflow tank and all good. Whats it tring to tell me?

Flashing is a built in feature that says you have a problem with the HVAC system. Unable to control heat/cold is usually the airmix actuator. Please do a search on "airmix" and you will find ALL the info you need to see if the actuator is moving properly as well as the way to replace it if it is not operating correctly.
