1996 Chevy Astro 6 cyl Four Wheel Drive Automatic 160000 miles
All of a sudden I have no Power Steering or Brakes.
I have checked the Serpentine belt and all is functional.
Is there a fuse that could control this?
I have a remote starting system in the car and I wonder if this could somehow cause the brakes & steering to malfunction?
The power steering pump provides fluid pressure for brakes. The power steering pump has failed. Check fluid level in P/S GM has know pump failures the shaft breaks. Hear any strange noise prior to loss?
Let me know
Thanks for donate

The problem is the Hydro-Boost on your van
Check the fluid level in the master cylinder. It should be within 1 / 4 in. (6mm) of the top. If is isn't add only DOT-3 or DOT-4 brake fluid until the correct level is reached.
Check the fluid level in the power steering pump. The engine should be at normal running temperature and stopped. The level should register on the pump dipstick. Add power steering fluid to bring the reservoir level up to the correct level. Low fluid level will result in both poor steering and stopping ability
*The brake hydraulic system uses brake fluid only, while the power steering and Hydro-Boost systems use power steering fluid only. Don't mix the two
Check the power steering pump belt tension, and inspect all the power steering/Hydro-Boost hoses for kinks or leaks.
Check and adjust the engine idle speed, as necessary.
Check the power steering pump fluid for bubbles. If air bubbles are present in the fluid, bleed the system:
Fill the power steering pump reservoir to specifications with the engine at normal operating temperature.
With the engine running, rotate the steering wheel through its normal travel 3 or 4 times, without holding the wheel against the stops.
Check the fluid level again.
