It's hot in here!.....
 

OK, I had my a/c worked on recently (blowing hot), dryer was replaced and all was good. Now after running a bit its like the vents close up and I have no air flow. I hear the fan running and the flow of air is not affected by movement of the vehicle. Sometimes it will come back after a while. I'm told this is a control head problem. Before I invest the money on a control head I was hoping to get some opinions about this. another thing that has cropped up recently is the airbag light will randomly turn on and off and I get the "Service Airbag" message on the dash display. There's no sequence as to when this happens and it will stay on anywhere from a couple of seconds up to a full minute. Whaddya think? Should I get some holy water?....
