Lost Power, Need Guidance...??
99 XJ, 4.0 AW4........
This morning on my way to work I lost power to my radio, wipers, door/window controls, heater blower, air bag light came on and no turn signals . Everything else functioned correctly as far as I know. When I parked at work I shut it down and then restarted. Everything functioned correctly. At this point I'd call it an intermittent issue.
Any ides as where to look? I'm thinking maybe a bad ground but maybe a bad relay? I'm open to any ideas....

Look at the connector on the ignition switch. Probably toasty brown.

All those circuits you named are fused in the JB, but different fuses.
I don't think they share the same ground point, except that they are all grounded through the chassis. Ground G106, on the left inner fender is the ground point for a few f those circuits, but not all.
I know you redid all your cables in the engine bay so it may be a good idea to double check the security of the grounds.
Double checking, I found that all the circuits you describe go through connector C4 in the JB. See JB diagram. It might be a good idea to access the entire JB and remove connector C4 and see if it's corroded. If okay re-secure. Any corrosion in the connector is bad juju.
