Help, anybody with an '04 Savana van?

I just bought an '04 conversion van. I bought the van new off the lot. The manual says it has Passlock and the window sticker does also. The manual says the "security" light on the dash is supposed to light up when you first turn the key to the on position and go off after a few seconds. My light has never come on. At first the dealer tried to tell me I don't have passlock when I questioned them on it. Then when I showed them the window sticker and the manual they said, "oh, I guess it does have passlock." Then they messed around with it for about an hour in the service bay and said, "it's all okay, that light only is supposed to come on if there is a problem with passlock." I asked them why the manual says it's supposed to come on when you turn the key on and go off after a few seconds and they said, "oh, the manual is wrong." I think they're lying to me and there is some sort of problem with passlock. Anybody that could check their '04 dash and tell me if their light comes on and then goes off would help me. Thanks.
