During the build of my '57 210 restomod, I began piecing together a custom installation of a VA Gen IV system. Prior to that, I had very little knowledge about the details on how an AC system worked, and all of the particular components involved. It was the first time I had ever touched an AC system, let alone do a custom installation of one. So, I had some doubts in the back of my mind when I started having problems with the system blowing warm when I turned it on. The problem frustrated me. Was it something I did wrong? I made the hoses using the EZ Clip system. Is one of the hoses leaking somewhere? The weird thing was, most of the time it blew warm air, but once in a while it would surprise me and blow cold. I had it recharged twice, and replaced the trinary switch once. I finally took the car to my mechanic friend's shop to have him check it out. The problem turned out to be so simple: the AC compressor wasn't getting a good ground! You see, I had the AC mounting brackets powder coated, and the compressor was painted with multiple coats of primer and paint. Honestly, I didn't know that it needed a ground. So, I sanded one of the unused mounting holes on the compressor down to bare metal, and bolted a 14 AWG wire to it and attached the other end to the frame. Bingo! Blows cold all the time now!
