Got my head down under the dash. I can see the blend actuator door moving when I crank on the temperature control. I can't see any way of moving it manually, however, as it's totally encased in a plastic box with no external handle of any kind. But that it's moving in response to turning the temp control suggests it's not the problem. The problem persists, and we just went through the hottest weather we've had since late last summer. I get maybe 30, 40 minutes tops out the A/C before it gives out. Guess I'll have to have the mechanic check out the system.
