Passenger sliding door would proceed to close , after latch lock would latch, a few seconds later, it would release. One can't lock car by key remote. Alarm will sound to indicate door is not closed, and dashboard display shows door open. only way to proceed to drive is to manually lock door, and turn off switch on dashboard to shut off alarm. Is there a known solution for this condition? Another condition worth noting is that is has been raining for weeks, and it may be water related. Drivers side sliding door works okay. Any suggestions would be appreciated, I am 1000 miles away from home on vacation.

Update from Sep 13, 2009: After I got home from my vacation, I did some research online about my problem. I have a electrical background, so I took the door apart to locate the problem. I have photos that I have taken of the door interior to help explain the fix.
The basic problem was that a mechanical circuit switch within the latch assembly was not being satisfied. Some water had made it's way within the door latch, and had corroded a spring loaded lever. This in turn, was binding the lever which was spring driven, and the switch was not being completed. It was painful to get to, but not impossible. After removing the complete door latch assembly, I was able to remove the corrosion and lubricate the latch and spring. It became functional again, and the circuit works without error. So if you have any mechanical knowhow, dive it and fix your own door. The dealer wanted to sock me with a 800.00 bill to replace the door latch assembly.
