2003 Astro van - power locks & AC issues...

Hi
I just bought a 2003 Astro van with 110k miles and I have two problems
1) When I shift to drive the passenger and the sliding door lock but not the driver door and when i shift to parking the passenger and sliding door unlock but not the driver door side and neither one of the power switches work. Any idea???
2) When I turn the ac or heater on no matter in which position I set it to the air comes out to the floor and windshield.
Any respond will be GREATLY appreciated. It’s my first van.

There is a vacuum line that goes from the vacuum reservoir (usually next to the bottom of the passenger side engine) up and across the top of the engine to connect on the driver side of the engine. The vaccum line cracks/leeaks and will not allow the vent vacuum actuators to function. Replace the line. Use a thicker wall buts same inside diameter rubber vaccuum hose. Probably under $5. People waste a bunch of time replacing the actuators, switches, etc. Its just the vacuum line and poor original placement/design.

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.

Loss of power after 20-30 miles on my '04 chevy 5.3

Battery died in 2001 astro van....


Some models of the astro were equipped with the security feature like your describing. If the radio is locked (meaning it doesn't work at all) it will be the security. Seems funny that the radio wouldn't work, but usually it locks it too. As far as I know, youll have to go to GM and have it unlocked.

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!!
