This is a common problem with Montana vans. Its usually bad wire which runs under the front passenger side carpet.
Check the other lock switch and see if it works. If it does you have a bad switch and it needs to be replaced. If neither one works you may have to take it to a dealer
Don't take it to the dealer! This is EASY! I just finished fixing mine. The remote worked fine, the key worked fine, but the switches did not, and I wasn't about to fork out dough for a switch I didn't need. Pull off the sill plate on the passenger side, and the kick panel. Pull up the carpet toward the middle of the van, and have someone hold it there. You will have to unravel a bunch of electrical tape from the harness.There are two wires (one white, one blue) that have connectors that go from one wire each to two wires each. Cut these connectors off and replace them with a new good piece of wire, about 5 inches long. Solder if possible, tape them up or better still use shrink wrap if possible. Tape up the harness, and put the carpet, kick panel and sill plate back in. Total time 15 minutes.

I had a 1999 Montana in which the door locks would cycle from lock to unlock, also when I turned on (if I remember the right turn signal). Took to dealer and they diagnosed the BCM (body control module) bad. I did NOT have them replace it due to cost. The problem was a bad ground connection for the BCM.
