I drive a 94 fleetwood. It just started today that the interor lights wont turn off when i start it up and drive. It also stopped locking the doors when i put it into gear. Also when the car is turned off and the door is open, on the dash a light that displayssecurity usually blinks. But they all stopped working when i went for a drive today. So i figure maybe there in the same ciruit. What should i check? i suppose my battery will be dead tommorow when i wake up. any input would be greatly appreciated.

 

well,it ended up being a loose ground.

 

loose grounds are common electrical ghost in our cars.
glad you nailed it ...
