The FCM is somewhere in the passenger compartment (in dash) location. The best solution is to take the vehicle into an authorized service dealership and have them diagnose this issue.

If you are looking for the fuse box diagrams or any other diagrams for your Ram, check promanuals.net for a factory service manual for around 20 bucks or so. It's an invaluable tool for my Ram 2500.

The AC relay is located in the under hood fuse box. The cover should have a legend for location. Its one of the bigger black ones. You can rotate it with the horn or ABS one to see if its the problem. You may have a small fuse also in that box for it. If this doesn't solve the problem then you either have a leak or a computer problem. What a shop will do is try with a bidirectional data scanner turn the AC on. If they can't get it to turn on with a scanner then you most likely have a failed PCM if they verified you do not have low pressure or a relay or wiring or switch issue.
