Maybe a leak in the vacuum lines under the hood, passenger side behind the battery. Check the hoses.

i am sure it is a vacume leak but i don't know where..if i have it on vent ,it works until you give it gas then it kicks back to defrost.

I've experienced that same leak location. I've also had to replace the vacuum pump twice. No problems since the replacement.
