A\C vacuum control valve

95 2dr 3.1, Vents stop blowing air upon acceleration. Suspect this valve. Anyone know where its located? Been told engine compartment or behind the glove box. http://info.rockauto.com/getimage/getimage.php?imagekey=887539&imageurl=http%3A//images.wrenchead.com/smartpages/partinfo_resize/DUS/15-50568.jpg

Might want to check the vacuum ball and hose, usually between the front part of the inner fender well and rad. support.

Is that on the drivers/battery side?

Yes.

Found a crack in a rubber elbow at the manifold area. Hope thats it.

Update. Hard plastic vacuum line that runs to vacuum canister under the battery brittle and busted. Replaced with regular vacuum line.
