Whenever I accelerate the cool air from the air conditioner cuts out. Release the gas pedal and it runs fine.

Do you mean all the air cuts out or do you mean the air goes warm?

The vacuum-controlled temperature control flap is moving when it shouldn’t. When you open the throttle, there is less vacuum, and the flap moves. When you lift off the throttle there is more vacuum, and the flap moves back to where it should be.

Start looking for a vacuum leak.
