My guess is that you have a vacuum hose to the HVAC controller that has come loose or else has a leak.
Thanks so where is the HVAC controller,is in the console or under the hood.Again thanks
Unfortunately, the unit is in the dash so access it a little troublesome; however, the vacuum source should be under the hood somewhere and be a lot easier to track down. That would be the best place to start looking.
Thanks for the information I'll take a look see.
