I have a 2001 chevy silverado z71 1500 lt, lately heater is only blowing out cold air
blowing out nothing but cold air, no hot air, fan blower works fine, seems like a
lot of the air is staying inside of the dashboard, every now and then you will
feel a little warm air, but not often, what can I do?
If the engine is running at operating temperature, and both heater hoses are getting hot, then it would be the HVAC blend door actuator that would be bad. hvac
