I have just finished helping a friend pull the dash to replace a leaking evaporator coil. In the process, we found five vacuum
actuators buried in and around the heating/cooling unit---four of the actuators would not hold vacuum (they should all hold vacuum) with problems that ranged from a tear to very small holes in the diaphragms. Since we had everything apart , replacing actuators was not that difficult. The bad news is that two or three of these actuators appear to be situated so that dash removal is the only way to get to them.
