GMC Vandura 2500 QuestionsAir only blows threw defrost or floor vents won't work door is opening and close (1 answer)
Worked fine than resistor went out now the air won't blow out vents I can hear the door opening and closing fine can't figure out if there is something else that controls the vents or not don't know where to go from here any help will be greatly aprecated think you
Only blows hot air even after putting freon in it.
Only happens when the engine has time to cool down, like overnight or even a few hours. I have to crank the engine and hit the gas pedal to get it started. Sometimes after I crank it will start but then turn off if I don't keep my foot on the gas. PLEASEE HELP!!
