i know this might seem odd, but a wile back the center vents stopped working. the sides still did, so i knew the system was not a total loss. i found a man that worked at a dealership here locally that fixed it the first time. it was an unplugged air hose. bestdes the obvious "go back to him" fix, there does not seem to be anything unplugged. the air still flows throughout when i manually engage the ? accumulator? under the dash next to the vents on the passengers side. two questions 1. how much vacuum pressure should there be in laymans terms coming from the tube when i take it off the accumulator and test it in the palm of my hand. not noticeable noticeable pulls the skin 2. does anyone know the installation sequence of the hoses to the back of the controls. ive noticed they have numbers. www.sk1pper.com vin #10246 ps looking for kirk brandon who owned a blue D. i still have his fathers license plate!
