A/C troubles

I have posted about this before along time ago. When I speed up fast the a/c goes off. Fan and everything stops(don't know if compressor stops or not). Heres what I've found:

about 50 seconds after the car is off the climate control statrs to loose vacuum. I removed the glove box and watches the diaphram behind it slowly close. I have checked floor diaphram and it is not leaking, I checked the center diaphram and it is capped due to leaking.

After the car is off I can turn the key to the run position directly after car off and the blower will start. About 50 sec. later it goes off and the servo clicks and so do the switches.

The tank in the fender holds vacuum.

Where is the main air flap to all the vents? Does anyone else have any other suggestions where to look. Do you think my servo is failing?
