My 2000 Mercury Sable Premium LS (3.0L 24V Duratec V6) has an electrical issue:
When I remove the key from the ignition, the instrument cluster and headlights do not run off. I can reach in at any time, regardless of key presence, and turn on the headlights or check the instrument cluster.
I manually turn off my headlights using the switch, but I fear the instrument cluster is draining my battery. It was hard starting one morning, so I threw the charger on it when I got home and found that it was down to 60-70% capacity.
How can I fix this, or is this not a bug but instead a feature?
