Hi everyone! I am new here. I have been doing some research and it seems that I have found others with a similar problem as mine. I have also found a few different solutions. I have a 1997 GMC Suburban that runs pretty good. About 6 months ago, my front/top air vents stopped blowing air. The feet vents work fine, as well as the two rear seat top/bottom vents. The air blows cold, and the heat works fine. Air also blows out of the defrost vent in the front. Sometimes the ac light comes on, sometimes it does not. Whether the light is on or not really doesn't make a difference. I took my Suburban in to get it looked at and my repair guy said that he just wasn't sure. He said that the gauge wasn't switching on when he turned on the air for the front vents. I am really hoping that this might be as simple as the air filter needing to be changed. I cannot afford much at this current moment in my life, but at the same time, I will just "die" if I have to go through another Florida summer without air conditioning blowing out of the top/front vents. I would love to fix it my self if I can, though I am not mechanically inclined, and would not want to make the situation worse. Thank-you ahead of time for your reply!
