Need a copy of the 2003 Chevy Astro Van Fuse Box Diagrams

look in fuse box ,try 4ways if they work follow noise to source you''ll find the others

Have you checked your freon level? The compressor will not engauge when the R134 level is too low .More than likely you need to recharge the system after 14 yrs you may have a small seal leak. Try picking up a recharge kit with a gauge attachment. This has worked well for me on my 3 Astros I currently own. Othwise the fuse box is on the drivers side left of the steering column.

Fuse panel is usually located under the dash by the driver's feet or under the hood.

It is in the Fuse Box, Go to www.bbbind.com and put your Car information in and you will be able to locate the Fan Relay....

The power for the data link connector is from a 25amp fuse Number 7 in the IP fuse box. As long as the check engine light is on the computer has power.
The main computer power is from two ECM fuses in the box near the battery.
The fuse locations should be in the back of your owners manual.
