My lights on my 1996 caravan won't shut off until the timer shuts them off and they turn on when any door is opened

I would start by pulling the door panel off the inside. This will give you a look at the lock and handle mechanism to see what is amiss. Suspect a broken, fallen link that may now be lying in the bottom door channel and retrievable with magnetic pick-up tool. Get a good trim removal tool since a panel that large is easy to mar if you try pulling it with a screwdriver. Have a helper assist with the job and start by pulling the rear and middle seats if you can. To cheat on this, you may want to pull the panel on the opposite door to see how everything is supposed to look.

does it have after market alarm or remote start/ keyless entry system in it? if so that is at fault

remove the panel from the rear hatch and you will notice a piece of the sound deadener has moved up against the power lock activater,the sound deadener is made up of a rubbery tar kind material that goes almost gooey when warm,as far as the key,keep spraying a penetrating oil inside the door lock and gently but forcibly work the key in and out and back and forth but do not twist too much and break the key off

I would check the iac(idle air control valve) first it controls the idle, and then if it is still acting up you may have to change the crank/cam position sensor

Replace the wire track harness in the lower door opening.
