I crank my heater on now and to my surprise it does not blow hot air. I can hear and feel the air coming out but nothing in the ways of warm. Is my heater core going out or what?? Please help guys. It is getting pretty cold here in Texas now!!!
there are two heater hoses on the firewall in the engine compartment, if one is hot and the other is not then your heater core is plugged or the heater valve isnt opening.
