There must be other situations too because mine is running even when Engine is running?
When climate control on HI, or in some other situations, too?
BTW, don't rule out the fact that some previous owner/garage messed up the wiring.
I need to verify the situations.
But about the HBV still so is there vacuum when it flows to heater matrix and no vacuum when it goes to engine?
Because that how it looks like when you look at it in pictures.
