Power locks and interior lights

Electrical problem 6 cyl Front Wheel Drive Automatic 130000 miles

1. The remote does not work at all 2. The power lock button on the driver and passenger doors do nothing when pushed unless the key is turned on 3. Interior lights do not work at all 4. Clock built into dash does not light up

Could it be a fuse?

All of this appeared to occur at once within the last day. My wife tells me the temperature/compass reading in the rear-view mirror acted up in the last day or so but since then has cleared up (99 DegF here in the day)

Check engine light has been on for a year and we're told it's the computer. That hasn't changed.
