Just returned from six months in the Middle East, and found the floor on the 2001 soaking wet. The driver door/ electronics work, but the electric door locks and windows do not work on any of the passenger doors. The keyless entry does lock/unlock the driver'* door, but not the passenger doors.

I have pulled back the carpet and found the wiring harness, but have not found where any connectors that are at the floor level. Thinking a connector is submerged in water and corroded, but can't find anything but solid wire runs.

Any idea where the connector may be or if I am off track on my diagnoses?

Thanks JW. The carpet is frozen, what a mess. I am thawing out the carpet. Went ahead and drilled a hole in the left rear passenger floorboard. This Bonny sits from time to time and I can't have water sitting in the interior. I thought I fixed the water issue months ago= but guess not.

sounds like you got your hands full. you might want to invest in a cover. letting them sit outside drys out seals and fades paint, your going to have more problems each time. ive had cars that sit for a while, the one time i had a mouse take up residence in my old jeep. it took me a while but i finally got it with peanut butter on the trap.

Do you have a sun roof?

No sunroof. But I did replace three of the four window regulators and think the water is coming through the driver'* door. I did reseal the plastic, but must not have done it right.

Here is the follow up on the problem. on the floorboard, underneath the rear of the driver'* seat is a wiring harness. In the harness is a white jumper box which connects qty 4 light brown wires with a white stripe. Inside the jumper box was all corroded. It was too corroded to clean, so all I did was cut out the jumper box, used a 14 guage piece of wire, and soldered all four wires to the jumper wire. Taped it up and everything works great. You have to pull the driver seat to do this, but pulling the seat is real easy, need a Torx 40 (size/??) and thats about it.
