Recently picked up a 2002 manual blk/blk. Tons of electrical issues.
Signal lights work on outside but not in dash.
No Signal Chime.
Radio would play when I took the key out but not with it in. No controls worked.
Radio display blinked and drained battery with no key.
Emergency light switch didn't work
Remedy was to take apart the center console and unplug the black connector going to the center box. Easiest way to achieve this is to remove the e-brake boot and turn the black connector to release and unplug the connector. Let it sit a few minutes before testing the radio/blinkers.
Hope this helps someone.
