Just installed an S&B cold air intake on my 6.7 and when I fired the truck up I noticed I had no cold A/C. The only thing I touched under the hood was the MAF. I heard that the MAF does something for the A/C system but I'm not sure. When I started the truck it had a high idle since it had to learn the new airflow. After testing every fuse in the truck and checking the wiring I was starting to lose hope, I even tried disconnecting the batteries a few times with no luck. I decided to plug in forscan and I got the code P06A0 - variable A/C compressor control circuit. It also gave me an ABS fault because of the PCM fault. I cleared the codes and had no results. I put the truck back to stock so i could take it to the dealer the next day, even when it was stock I had no cold air. I got half way to the dealer and decided to try the air again and it worked perfectly. It seems weird that just letting the truck sit overnight fixed it. I ended up putting the new intake back on and everything works great now. I remember one time before all this when the A/C wasn't working and all I had to do was turn it off and back on. I'm not sure if this is directly related to the new intake or just a coincidence. Anybody have this issue?
