If I'm seeing your diagram right then I'm guessing if I remove the the glove box and find the "33" vacuum actuator I'll find what's wrong. I don't think I'm lacking vacuum there but I'll check. Thanks for the diagram!Are you getting vacuume to the heat defrost control shouldn't there be a vacuume line going into work the servo du-floper thing lol number 33 in picture ?
Thanks! I was hoping for a photo but I do appreciate any help I can get.Don't know about Chevies, but on Olds, the Defroster Vacuum Pod (blue hose) is just above the gas pedal area and right above the floor/dash vent diverter vacuum pod (yellow hose). I think they're in the same location on Chevies, but I'm not 100% sure. Parts diagrams are not the best thing to use most of the time for locations of some of the items. This is one case it's true.
