HI guy,s it,s mike.I cannot get my ac to blow out of the vents. Air only comes out of the defrost vents and floor vents.last year i took off my dashboard and my blend door was vacuum shut.I had to really pull hard to get it open.Now it has happend again.i checked the vacuum lines,the round dial switch on the control.i hoping i don't have to pull the dash again.if so i will replace the blend door.Thank,s guy,s Mike
