Car has been sitting for about a week. Had trouble starting it because of recent rains and I know I have to change the cap/rotor/wires. After letting the engine bay get some air, it started right up fine and runs fine. But now I notice the following accessories/functions have all gone caput simultaneously:

- wipers
- blower motor
- cruise control
- radio
- horn
- power/heated mirrors

These were all working normally the last time I operated the car.

Tried searching here, and could only find a few short posts, mostly from 700s. Similar symptoms appear to have to do with steering column grounds being loose, or a loose/faulty ignition switch.

I examined the fuses carefully, and rotated the ones that are associated with the various non-functioning mechs. All the contacts appear to be excellent. Just earlier this summer I cleaned all engine bay/battery ground points, and they all look very clean.

Is there anything else I need to be checking here?

Thanks very much.
