New XR7 owner with Question about A/C

Hi, i just recently purchased an 89 XR7 SC auto w/ 38k orig miles. The A/C was recharged using Freeze 12 which works good. I get nice cold air but I have noticed that at certain times when I punch it and get into the boost, the A/C likes to stop coming out the normal panel vents and start coming out the defrost vents. Any ideas why this is happening?
Thanks in advance,
Derek
 
answer

When you go into boost that takes away any vacuum and if the vents are controlled by vacuum then you will that setting untill it comes back to vacuum.

The defrost is the original setting and vacuum changes it for vents and all the other features. When you floor it you also the ac is kicked off for more power also.

Cheers
