Im only getting high heat out of car vents no matter what I select on climate control selector. A/C works but its just not blowing cold air into vehicle. On heat selection, I cannot control heat either. Could it be blend-door broken or stuck in heat mode, or the blend-door motor failed, or cliamte control selector failed?

Could be the air blend door stuck in the heat position, blend door motor and the HVAC control module
