If yours really draws 500ma, that's 6amps after being parked overnight or the equivalent of running with your headlights on for nearly an hour. A new unit would be a good eco mod.

Yeah, it's a 1993 factory AC Delco model.
It's not even the worst offender in the car.
The premium systems in the car use a lot of juice too. I guess the reliability of cold start electronics was low then. My power seat controls/system is always powered so it can auto adjust based on the keyfob used (set per driver) before they sit down when they unlock the car.
The exterior key lock is always lighted, run by a 15w bulb and a long length of fiberglass filament; kinda creative before LEDs existed.
And there is an air compressor that inflates the rear shocks as a ride control mechanism. It's not air tight so it is also always on, and occasionally runs to push the bladder back up while sitting.
I have climate control, but it still uses the resistance elements for fan power.
