look under the hood there should be a box with all the fuses it will be under that box, if not open the driver side door, and it will be on the side panel to the left of the steering wheel

should be a relay , left side fuse panel under hood

Replace the steering rack

google Where is cylinder #1 on 06 dodge 3500 diesel

P1274-a/c Clutch Control Circuit 2 Open You will need the help of the dealer or a factory wiring diagram and diagnostic flow chart to fix this one. I can't find a clear cut answer other than someone that used a fuse for the AC circuit to power another system and the fuse blew out.

need new pump

Did you ever find the relay? I was told this pickup does not have a control relay for the AC clutch, but not totally sure.
