i really dont see how that they can say that, when you make the L83 compressor work 100% of the time, and its wired like factory c-10 with low pressure switch, how is it going to freeze up? low pressure switch activates and opens circuit....

vintage air system does not communicate with the GM computer from what i remember looking at their instructions on the last install (on a 86 c-10 with l83). Vintage air is completely separate. On the L83 swaps Ive done, ive had no issues with evaporator freezing up with stock compressor and wiring it properly.
