I went to bulldogsecurity.com and looked up the wiring diagram for this vehcle. However, prior to checking this part, I would check to see if you have a blown fuse. It doesn't hurt and only takes a few minutes. There should be a fuse for that either somewhere on the side of the dash or near the brake pedal area. If not it may be under the hood, but it should be inside the vehicle. You may have multiple fuse boxes. If it has (2) sliding doors it will have a wire for the auto doors in each kick panel (under the plastic trim/molding) when you open the door and look down you will see all of the trim/molding it should snap out or may be held in place with a screw or (2). Once you remove that you should see the wires. It says for the left side it is either light blue or black and the right side is definitely light blue. Trace this wire until you find out where it ends (the motor or switch to control the auto doors) Then test the switch/motor to see if it is bad.
