HVAC Shuts When Auto Start/Stop Kicks On

[PrepVet]

It’s happen a few times this week. I will come to a light and stop. Auto start/stop will turn off the engine then when I let off the brake the car will restart but shut off the blower and it will not come back on. I have to flick the speed control up or down for it to come back on.

Is this going to be common in cold weather? So far it is not a big deal just annoying.

Sounds like a vacuum issue.

The Blend Doors are not vacuum actuated any more. I would recommend seeing your dealer. I have not noticed this issue on mine.
