Radios naturally come with am, so it will always work so long as there's power to the radio. Fm, however, is a built in receiver and if they break or start to break, then you will lose power to your fm which it sounds like is starting to happen to you.

A/C sounds like an issue with the a/c module which is unusual. There used to be a test sequence on the earlier a/c units not sure if it is on the 4.2. Check all fuses there are four fuse boxes. one at the end of the dash by the door and two under the bonnet. the radio/cd player etc is all one unit (medIa unit), that would explain why they all are not working. I think the a/c fault is connected to the media unit but not sure how. Need to study the wiring diagram for this, I take that it is a 4.2. Jaguar diagnostics will show the fault or give a lot more guidance. Generic scanners wont pick up the fault codes for things like this they are manufacturer specific. That's how manufacturers lighten your wallet. website jagrepair has all the electrical diagrams free.

It may just be a short in the wirering

there is a fuse in fuse box that powers radio...sounds like a problem with radio itself....if fuse was bad it simply would do nothing"no power at all.

DOES THE RADIO PLAY? HERE ARE THE FACTORY WIRING COLORS FOR THE RADIO HARNESS, RECHECK YOUR WORK. IF U FIND NOTHING THEN IF THE RADIO PLAYS THE CD PLAYER IS DEFECTIVE, IT HAPPENS BELIEVE ME.
