Power Door Locks Unlocking Randomly

I purchased a used 2000 Montana with 47,000 miles on it. It seems to have been kept in very good condition by it's one owner.

A few days ago, while driving, the doors started unlocking themselves, at random. Sometimes, it happens only once in a while during a drive. Sometimes, when it's at it's worst, it happens every few seconds. Sometimes, I can take a trip and it won't happen at all. It's getting annoying.

Anyone have any ideas? :eek7:

I'd suspect a faulty switch that either isn't staying open like it should. Try disconnecting one switch, then the other for a period of time to see if it goes away.
