[THEGTOCHISM]

working on the wife's 84 g-body. I replaces ac compressor ,dryer, orifice tube, flushed everything, new seals, pulled it down real low for 1 hr. added the r 135 change and it cooled great! for a week . Problem is now it blows only hot air out the ac ducts on max. hooked up the gauges everything looks great. i am thinking heater hot air door stuck open. . or cable related. Temps here have been swinging from heat to ac, where i live so i have moved the controls a few times. anyone got a idea or picture of the duck works?. is it cable controlled? i see it has a lot of small vacuum lines in the engine compartment .going inside the cab.
