It sounds line a connector somewhere is loose or off or a common fuse.
Check the wiring diagram and trace it to see where all of these systems share the same connector or junction box.....

OK, I checked the TSRM wiring diagram and those systems are on the same line.

If I am reading this thing right, it could be the Pwr CB #14

Located in relay block #5 on the drivers side kick panel.

If you have an ohm meter, check the power at the CB receptacle in the relay block to see that it has power with the ignition on. If it does, then its probably the CB. If not, then you might have a bad connection upstream or at the relay block.
