Question Dash Air Conditioning Problem: questions


I need help trying to resolve a recent issue with my 2002 Beaver Monterey dash a/c. I was checking the dash controller after installing a new dash and I heard a bang. It was the air diverter slamming shut. Now air only comes out the defroster vents. The heat and a/c function is normal. I took out the control panel and found a broken vacuum line. I repaired that, but still no airflow except the defroster. What am I missing? Is there some way to check the controller? Is there a breaker I could be missing? I am ready to take it to a specialist, but thought I would give this forum a try.

You say you "repaired" a break, I hope you mean you replaced the entire tube.

If one part was old & brittle enough to break, the rest of that tube's no better. There's likely at least one more break in it somewhere, it certainly sounds like you have no vacuum to the part in question.

Maybe you already know this, but the default (no vacuum present) position of the AC/heater is to the defroster?

That's where I would start, verifying you have vacuum present at the controller?

At 11 years old the vacuum hoses should all be replaced if one went bad. Bulk hose is inexpensive, then you cut to length yourself. When I have that trouble, that's what I will do.
