HVAC issues
ok..so i just did an A/C delete on my 88 Roc. when i change the controls from off to on it works just fine...all low-high works on the blower. but it will not change off of defrost(the lever moves just fine) is this vacuum controlled? i know there are two vacuum lines that enter just behind the motor and i know one has to do with the A/C (coolent routing solenoid, did the delete on that) so is it possible that the other line is for changing from vent to heat(feet), face and any combo there....
