astro van brakes go on by themselves
when i start the van the brake pedal goes down and the brakes lock on when i turn it off the brakes free up

The Chevy Astro Van returned unchanged for the 2004 model year after a number of small alterations involving brakes and trim levels for 2003. The midsize truck-based Astro offers buyers a choice of rear- or all-wheel drive, different rear-door layouts, and a cargo van interior configuration.
The Astro has been praised for its towing capacity, versus that of a minivan similar in size, thanks to its truck platform. Other positive attributes include interior space, interior cargo-carrying options, and the all-weather traction system bundled with AWD. While moving cargo and loads may be a snap for the Astro, its ability to move passengers from A to B is the downside. Ride comfort and handling are both substandard, and no side-impact airbags are offered.
Astro vans come standard with a tilt steering wheel, cruise control, and full power accessories. Seating for eight passengers is available through two front buckets and two rows of three-seat benches. With the second- and third-row seats removed, cargo space totals 170.4 cubic feet. Buyers may also opt for a seven-passenger configuration with the LT package, which swaps two second-row bucket seats for the bench. The LT is also available with optional leather seating.
The Astro is powered by a 4.3-liter V6, which produces 190 hp and is paired with a four-speed automatic transmission. The drivetrain is available with both rear-wheel and all-wheel drive configurations. The difference in traction is significant, as the rear-wheel Astro struggles to maintain a grip on wet surfaces, and the AWD version is bundled with traction control. Fuel economy is estimated at 14/17 mpg with AWD and 16/21 with RWD. The rear-wheel setup offers the best capacities; payload is 1,764 pounds and towing is 5,400 pounds.

My 2004 Chevy van is not doing nothing when I turn it over and the battery is good
Chevy Astro Van, 2004. All of a sudden, the doors locks quit working. They make a clicking sound and you can see them try to move, but they will not activate enough to lock or unlock. I had a short in the wiring about the same time they started not working, which caused several codes to show when the check engine light came on. The short is fixed, which was a hot wire that went to sensors, etc. It ocurred to me later that this could also be the problem with the door locks, and that is why I am asking. The doors locks started acting like I described all at once. Thanks for any ideas.
