Electrical problem

PONTIAC GRAND PRIX

'93 Pontiac Grand Prix. Not long ago my brother took out the subs from my car ever since then the interior lights will not go off. Both door lights and the light under the dash stay on 24/7 so everytime I use my car I have to remember to disconnect the battery so it wont drain. We tried putting tape over the end of the wires in case they were touching but it did no good. I'm not sure if it is from the subs being taken out or if there is something else i'm missing. If you have any ideas please let me know.

Thanks

You have a ground somewhere in the system. All of the lights are tied together, and they are all looking for a ground to light up.
It could be a bad door jam switch, and if you can pull them out and disconnect them to eliminate them one by one.
There is a possiblity that when he messed with the interior trim he might have accidentally screwed a screw thru a ground wire, which would ground all of the lights at all times. You may want to take out all of the screws or trim and look for any wires that may be shorted to ground.
Remember if you want to see if you fixed the problem, you have to close all of the doors and wait for the lights to go out.
