bearings frozen in the pump, maybe. It only works when the pump turns...... Number One: Check to be sure the belt is tight, If you are hearing a squeal, the belt may look tight but not be. The serpentine belt has a spring tensioner that I have seen fail, and the belt was just barely tight enough to stay in place, but would not turn the Power Steering pump at times and it has to turn that pulley to pump the fluid, or no power assist to the steering will occur. Number two: Power steering pumps have internal parts that will fail, and cause the loss of internal pressure. It may just be bad. Number Three: If you are not good at mechanic work...Please take it to the best shop you can find. You need smooth operating, power assisted steering at ALL TIMES. There Is No Fuse to Blow. Power steering by Chevrolet is still by fluid/pump.
Did you check for a blown fuse?
A blown fuse may be the reason a horn is not working in a Chevy van. It could also be caused by a faulty horn relay.
Blown fuse? Refrigerant leak?
If all the windows quit working you need to look for a blown fuse in the fusebox.
In the 1993 Chevy Caprice there is a brake sender located inside the steering column where the brake pedal is attached. Perhaps the brake lights are not working because of this, when a person hits the brakes. There could also be a fuse blown or a broken or shorted wire.
Getting your electric power steering pump to work is dependent upon what is causing the power steering pump to malfunction. In most cases replacing a blown fuse will alleviate the problem.
burned out bulb, blown fuse, wiring
sounds like a fuse is blown
You know your car has blown a fuse if whatever the fuse is for suddenly quits working. For example if your radio is playing and for no reason quits it may be a fuse has blown.
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
Defective horn, horn switch, or blown fuse. add to that a possble faulty clockspring in the steering column.
Be sure the bulbs are not blown.
