The under-hood electrical center (often called the fuse block or junction box) in a 1994 Chevy Astro van is typically located
on the driver's side inner fender well, near the firewall. It's usually a fairly large rectangular box with various fuses and relays inside.
However, it's always a good idea to check your owner's manual for the exact location and a diagram of the fuse box. The manual will provide the most accurate information for your specific vehicle.
