Vaccum control solenoid

My HVAC system would only blow through the defrosting vents so I traced the vacuum leak to this solenoid. I took the solenoid apart and found a torn diaphram, causing the air leak. Would this part be wants causing my HVAC to only blow air through the defrosting vents? I rigged a vacuum line that bypassed this straight to the HVAC system and I was able to switch vents.
I just want to be ordering the right part the first time. I am 99% sure this is my problem.

I just had to replace an intermittent solenoid (same one). That solenoid also controls vacuum to the 4WD auto hubs. My 4WD would very occasionally refuse to work in automatic mode.
Last week it died and stayed dead long enough to trace the problem to that solenoid. Easy fix but sometimes frustrating to track the problem down.
