Once in awhile is normal. Let it go until you have a dead battery.

That is true for some bonnevilles, but not others. 92/93 run with the key OFF. 95 doesn't. Not sure where 94 fits in, but I'm assuming it'* like the 95.

The pump you are talking about, is it the one located next to the intake? The compressor located at the front drivers side of the engine bay, above my evap canister, comes on every once in a while... Even if the car is off, usually just after I shut it off.

Likewise and not to sidetrack the post. My 95 Ei didn't need the key for ELC operation. It was hot at all times.
