Hi all. I tried doing a search but was not successful. Probably my fault. Anyway, I discovered today that when I change the position of the vent control dial, (it's a 2004 230 kompressor) the air flow never changes, it only comes out of the dash vents. Not the defrost vents or the floor vents, only the dash vents. Anyone have this problem before or know of a way to check/fix this? I have had the control module out of the dash to investigate a problem with the lights behind the dials. Could I have put something back wrong? I've only had the car a couple of months and its been hot as you know what here in NC, so I have only been running the AC. Was just messing around today when I discovered this problem. Won't need heat or defrost for quite some time, but I would like to get it fixed before I do. Thanks!
