i have a 1999 sport cherokee, and the windshield wipers, power windows, and radio(pretty much all the power options) constantly stay on when the key is out of the ignition. i put in an aftermarket radio and noticed all theses things happening a week or so after i installed the radio. i used a wire harness adapter from walmart. so i didnt cut any wires. its finally taking its toll on my batterie, also is the interior ligt suposed to come on when the front doors are open?
