i have the hvac box out from dash, I'm going to replace the evaporator and noticed that some of those vacuum 'pods' are not holding vacuum anymore. forgive the terminology but they control flaps in the hvac box to direct air flow. i need a picture of the box with what each one is called so i can order a couple of new ones... thanks ahead of time...
