Air flow through the cooling vents shuts off during acceleration, but it sounds like the blower is still running. As soon as the accelerator is released, air flow resumes. Does anyone have a suggestion as to what is going on?

Check the vacuum reservoir behind the battery for a unplugged vacuum line, a crack some wheres in it, or the check valve having a issue with it going to the a/c in the vehicle is most likely causes
