My van has an alarm/immobilizer system which I believe was an option you could get when purchasing an Astro. The manual describes a valet switch you can use to disarm the system, but doesn't say where it is. Anyone know where it might be? Thanks.

it is ussually under the dash by the fuse box or under the carpet drivers side by the kick pannel

Found it.
It's a tiny tiny button that was glued to the OBD connector housing.
