My wife Astra 2002 Power Steering failed and battery light came on.
Now and again you could switch off and start up again and it could go off.
Another time in this could weather we would start car up and leave to warm up for some time we also found battery light went off and power steering came back on.
We have just brought this car and returned it to the garage where a new alternator was fitted and no problem ,100 amp type so must require some power.
So I can only think that e.g. you are getting 4amp ect from alternator and you need 5amp to run the power steering pump motor then this could be why, by the way all lights ,heater rear screen ect were put on and headlight did not dim but was still the alternator.
The weather is also very wet and the alternator fit under the car, although there is a cover when hitting water it could still enter the alternator.
I hope this helps some of you If not all with these faults .
the most likely cause of that would be the power steering pump failing.
Your power steering will fail because brake fluid is poor lubricant.
no because power steering is a hydrollic assist system
That means you have a leak. Eventually your power steering will fail (no longer have power assist) and your pump will burn up. You can put some power steering fluid plus stop leak (all in one) in it, but I would also recommend that you crawl under the car and look for the leak.
This means you have a fault with your power steering. You should contact the garage as the power steering may fail.
what failed? the power steering or the mechanical part? power part, like driving a car w/ no power steering but harder to turn. front end part failure? buckle-up
The main cause of a power steering pump failure is a way to gasket. Electronic fuel pumps can fail due to wiring problems.
Noise from am power steering pump can be caused by several things. The fluid could be low, the belt could be loose or the pump can be beginning to fail.
Three main risks are associated with power steering leak: 1) Loss of easy steering capability 2) Low amounts of power steering fluid can cause the power steering pump to fail, which is another expensive item 3) Risk of fire with the fluid being dripped on the engine
It means theres a fault with the electronic power steering. DO NOT ignore as it can fail at any moment leaving your car with no steering!!!
There are a couple of reasons. First, the pump that supplies the hydraulic assist to the steering mechanism could fail. Or, the belt that runs the pump,if separate from other accessory drive belts, could fail. Or you could have a fluid leak, which in turn could cause Reason #1. Have a mechanic check the car out.
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.
