Re: 1971 Stepside LS Build

After two long years of tinkering I finally have the AC going! Seemed like everything I tried was a dead end and just couldn't get it to blow cold. Finally, I decided to go back through all the wiring I was sure I had done perfectly the first time. Well, I didn't. The fan switch in Vintage Air's diagram is labeled B>H>L for the prongs top to bottom. Turns out that is upside down on the actual fan switch. Flipped the wires and COLD AIR!!!!

I should have paid more attention to that detail when I was under there the first time.
