1999 Chevy Astro Van. Don't know exact model # of


You should have a 4l60E in your astro van. Which is electrically controlled, so no vacuum modulator. However, to address the ventilation selector not working... look for a vacuum line exiting the firewall and going to the passenger rear of the intake manifold. You will likely find it broken or disconnected there.

1994 Chevy Astro Van- four wheel drive


Sounds like the auto shut down relay. Located somewhere in the front grille/bumper area. Relay triggers on impact to shut down all power in order to prevent fires etc. Great idea but can cause exactly the frustration you are having if you don't know it's there!!
