Even if it does not work the controls still need vacuum to operate the zone doors, defrost / dash vents / floor.
Yes do so. Because he has AC and I cant remember were the vacuum tank gets it's supply from. Check the tank / metal juice can for leaks, mine had rusted pin holes so the motor had a vacuum leak.

Nope we are totally on the same page, my thought is something on the tree on the fire wall is leaking or the tree is it's self might be leaking/cracked.
