Vintage Air SureFit Condenser Kit 21567, for 1967-72 C10 and C20 Chevy & GMC Trucks

As I recall, these trucks recirculate air through the kick panel vent and the air travels through the cowl. I followed the path and that sends the air through the outside of the vehicle and has the potential to warm the air. There is a cowl vacuum activated door that must be in working condition for recirculation to work. That being said, this path has always worked and guys on here say it should not matter and a good working system should freeze you out anyway. I went ahead and created a path that does not go outside for recirculation. I have not tested it yet. Another thing is that you might want temporarily disable your heater to see if there is heat affecting your cool air. I live in Florida so the heater is seldom used. Most newer cars have the condenser right up against the radiator and electric fans. I may have missed it but what compressor are you using and is it new?
