I just got my A/C repaired a couple days ago. The center "flapper valve" was found to be inoperative so no air was comming from the center vents. Air was coming from the side vents and alot from the defrost vents, causing the windshield to fog up. So I removed the dash and reconnected the vacuum switch to the flapper valve. Now air comes from the center vents, but a good amount still comes from the defrost vents. Climate control set on normal, MIN temp, and fan on high. Is the normal? If not what caused this and what will cure this?
Thanks, Kevin
