No, I the light wouldnt dim on any of the in cab fuses. Then I moved to the big fuses under the hood, when I pulled the interior light fuse it dimmed or it was another fuse like ind lights or something... Cant remember, will check tomorrow
But what gets me is what would keep the lights on even after the key is out, its like the car is still getting some signal from the ignition lead...

Okay, The lights when you turn it off that are on very dim are the same as the ones when you turn it to ign. Do you think that the ignition switch might be broken?

I'm going to guess here that possibly a ground for the sound system is not really grounded, and power from an always-hot supply to the stereo (e.g. for clock or tuner presets) is backfeeding from the sound system'* ground through all the other components that are supposed to share that ground connection. e.g. if there'* a switched power source as well, the current is backflowing through that circuit to seek ground.
I would start by doublechecking any aftermarket wiring connections. Ground wires from the aftermarket unit should be connected to actual sheet metal, not just any nearby wire that happens to be black colored.
You might try disconnecting the stereo for a day or so and see if that makes a difference.

i just figured out a similar problem with my car..........the relay or part of the power antenna was drawing power............put the sucker up, and disconnected it......no more draw

the power antenna is disconnected
anyways
I'm suspecting something funky with the aftermarket installation. Something hot is running in series with the dash lighting, and with enough bulbs powered in parallel like that, they'll manage only a dim glow. If it'* a slow drain, it could have been days if not weeks before a fresh battery started showing major problems.

Thanks, that seems like it could be a very good possibility, I will take out my cd head unit and try that out, if that does the job it will be nice, but if it doesnt Ill start taking the dash apart and looking around.
