Every time I ask a question I never get an answer just a request for donation. Whats up? My question is no matter what temperature I set my heater blow cold air.

Do you have any coolant leaks? Ck the heater control valve, see if the vaccume line is off or broken, its behind the intake by the firewall, replace it if all ok
