So I was driving home yesterday. The car seemed fine. The cassette player was skipping a little. That was about it. When I pulled into the driveway, I shut the car off and the interior lights wouldn't turn off. Waited a couple of minutes. Checked all my light switches. Turned the car on again. Then all my problems began.

I touch the brake pedal, the interior lights come on. I accelerate they come on. I use the left and only the left turn signal and they come on. I turn the headlights on and they come on. I put the car into gear and the lights come on. Sometimes they go off right away, other times they stay on and flicker.

Does anyone know how to fix this?
 
Intermittent electrical problems are hard to diagnose, even with an automotive electrical specialist shop on site. Nearly impossible on the internet.

your issue sounds like ground problems or your BCM Is very not doing well. i would start by checking ground wires for your battery and and engine bay.
