Had a similar problem. remote would not work doors and inside switch would not work on passsanger side. There is a part below the passanger side door window and lock switch called the PDM or passanger door module.capable of some really strange behavior as it basically is a mini computer and rf signal receiver. May try reprograming your remotes first, if that doesn't work get new PDM. need to give VIN to parts folk to get it. Think it was about 200.00. Need to remove passanger side door panel and then take apart armrest with door swithes. Kind of tricky. funky screw on the front which has to be loosened and door panel must be off to get to it. anyway after install reprogram the remotes to the PDM. It involves off on, off,on ignition while holding down the unlock door switch, then hold the unlock on the remote?????? the sequence in on the net just search it out for your year.
