Change the thermostat in it,

heater control valve

have it checked with a computer by a tech, ther is alot of circuits in airbag systems

you can check a few things. first in back of the engine are 2 hoses going to the heater core , touch them and see if they are hot. they are the heater core is good. if they are not then the heater core is blocked. but i am guess the blend door in stuck closed and you may need a blend door motor

remove door panel.and see if gettin power to motor gettin power.motor no power look for broken wire or switch

Sure the culprit is in the HVAC system. The cover under the glove box needes to be removed to look and see theres a relay panel and motors that move the air doors inside the duct work the motors are on the out side and can be diffacult to change so even if your going to hire the work done it might be nice to look first so you'll know if your talking to a person that should do this work for you Quizzing the professional sales person at your local auto parts store you'll find the person that they know that buys the parts that fix these things if he buys lots of this kind of part that shop is likly to have a person that can go right to it and fix it cheap and quicker than someone puzzeling over the repair manuel and trying difference things with your money
