NEED HELP DESPERATELY!!!

When I parked my VX this am , I turned the lights off along with the engine. It had run fine.
Came out noon time to find my side marker/parking lights on . Checked the light stalk switch and it was in the off position. BUT...these lights were on anyway!!

The headlights still worked, the alarm(isuzu when bought) still armed and disarmed ok. Tried to drive and it bucked stalled and all the warning lights on and off...
SOUNDS LIKE AN ELECTRICAL PROBLEM...BUT is there anyway to home diagnose it. I'm sure the dealer will rape me like usual....if I bring it there.

ITS STUCK IN A PARKING LOT!

I'm in NNJ...anyone know a mechanic who can handle this and doesnt charge an arm and a leg?

Any help would be greatly appreciated!
