2003Montana, power sliding door open by itself in the parking lot

[qw7301]

Not sure if anybody had this before.

This moring, my co-worker told me that my 2003 Montana had its passanger side power sliding door wide open in the parking lot. When I went there check, the power sliding door was open and the other doors were still locked.

I am 100% sure that I locked the car when I left the parking lot.

What could have happened? A problem with the montana itself, or maybe some other remote controls triggered this?

Any ideas?

The door shouldn't open with the other doors locked. Is it possible when you locked the doors this morning that you bumped the side door at the same time you were locking them?

yeah, I think that's possible. I'll wait and see if this will happen again.
