posted something about it a while ago but I didn't get any replies.
my heater blows cold air, can't figure out why but I do know that the heater core does not leak, I checked that out first. the heater core hose's do not have much pressure in them. is there a heater vavle or something that opens and closes?
only thing that I can think of is the actual heater/ac control unit is kind of broken, the lights flash all the time for everything and the little screen with the numbers only works sometimes but the buttons do work when you push them because I can hear everything get louder when I turn up the speed and change from vent to defrost and all that good stuff...
anyone got any ideas? can someone post a diagram of the heater system or something?
thanks very much!
