How do I isolate the climate control to figure if there is a leak in that system? I already did locks, EGR, Cruise control.
The Climate Control is not working properly and when I shut off the car I can hear an air leak in the dash. Like a fkn balloon! pffffffff...!

Well there's bank of vacuum-electric servos behind the CCU push button unit. The control the opening/closing of the various vents. But with the pump not turning, the only vacuum source would be the reservior in the trunk (under the rear deck). Not sure, but I think the line runs from the tank forward - under the right rear seat, under the carpet inserts, under the passenger seat, then up behind the dash. Once you locate that line, you should be able to follow it backwards to the leak
