>What refrigerant are you using? R12 or R134? > >D^2 I'm using R12 (only because I have a Camaro that is headed to the scrap heap and it happen to have enough R12 in it to charge up the Imp). The system sure does get cold enough! It gives me confidence that if I ever have to switch to R134, the performance will still be acceptable. The problem is that when I hot wired the A/C electrical in order to bypass the missing AutoTemp II controller the easiest way to do this was to enable a single fan speed. Since I live in Phoenix, (we're expecting a high of 110* today) I of course used high as the speed of choice. It's great for the first ten or fifteen minutes while the car cools down inside, but after that I'm freezing my jewels off! I either need to get the ATCII controller working, or find a manual A/C dash control and replace the AutoTemp II controller like Kerry did. I guess another option is to install a temp controlled switch that will cycle the compressor when the blowing air reaches a certain temp. This would tide me over 'till I can either get my crusty old ATCII controller to work, or find another in working condition.
