I've asked questions without reply, so I'll try again.

1) I just replaced the vacuum pod for the defrost vents

2) When I press the "EC" button only air comes out of the center vents. Works like it should!!!!

3)When I press the center button for vent air only, I get leakage through the defrost vents, this is not right.

The vacuum pod is new, and I've already tried another A/C panel.

Is this a switchover valve problem????????????????????????????????????????
