You seem to have a knack for troubleshooting so no need for frustration.

While, identifying a vac leak is a labor intensive job, but no way near $400/900.

I would say your VCM is fine; but leave your finger at VCM's stem a bit longer, say 2 -3 mins and see if it holds.

Turn the rear A/C switch to A/C and check if there is vac suction at the end of the rubber tube that you removed from VCM. To do this, hold the end of the tube flush against the back of your hand and feel for "sustained" suction. Absence of sustained suction would mean vac leak.

For your front A/C control, two VCMs are mounted just above and to the right of the gas pedal. First, check to see if vac lines are connected to them. Second, do the finger test as you did with the rear VCM. Third, change the A/C switch.

Good luck and please post back.

Does that mean that VCM is good, and the problem is the leak somewhere along that white line? Or not necessarily? Thank you.
