Hvac problem

[KWT2000]

hey all, well got my A/C fixed today and it is working good..

but now there is another problem..

at idel the air comes out the vents like it is suppose to but under moderated to hard acceleration it goes up to the defrost then when you let out of it, it slowly... returns to the vents...

also when i turn the key on after sitting it is always blowing out the defrost no matter what setting until it idels for a bit


any ideas on where to look??

TIA

Check vacuum that comes from the intake and goes to the ac controls, make sure you are pulling enough vacuum from the intake, use a vacuum guage, also make sure the vacuum tree at the controls are tight and are not leaking

also look at the vacuume line that goes from the PVC line to the intake I just did one yesterday on a friends truck 03 120000 miles hole in it
