I have a 2002 dodge ram 1500 that is only blowing heat. The **** that controls the fan speed operates but the **** that controls heat and cool doesn't also the **** that controls the air direction(floor or front vent or defrost) doesn't work. Also the a/c button and the mirror defrost don't work. I've replaced the whole temp control panel and it still don't work. I also replaced the ignition tumbler and ignition switch!! Please help me

 

Sounds like your Heater Blend Door Actuator is bad, common with the ram trucks.
