What year , make , model vehicle ? Warning light , electric power steering ? And what would you like to know Allison ? How to fix or what to do ? If your vehicle is a GM product , Chevy , Pontiac , Buick etc... there was a recall on a problem they had . Your best bet is to take it to a dealer .
1. Check that the serpentine belt is still intact and still in position over all the pulleys on the engine including the power steering pump.
2. Check the power steering fluid level. If very low or empty you obviously have a significant power steering fluid leak which could be from a ruptured flexible hose, a leaky hose connection, a leak from the power steering pump itself or leaks from the fluid seals in the steering rack. If the PS pump has been run with very low fluid it will have been pumping air and will be damaged.
3. If the PS pump itself has failed you will obviously lose PS assistance and a bad pump would need to be replaced.
4. Since you have not checked anything on the car no one here can tell you the likely source of your particular PS failure.
5. The steering wheel should still turn but if the car is not moving it will be extremely heavy and difficult to move.without PS assistance so don't attempt to drive it in its present condition.
Heavy steering (not caused by neglected low tyre pressures) is usually related to a problem or failure with the power steering pump system.
Items to check on the Power Steering (PS) System
1. Is the serpentine belt slipping on the power steering pump pulley because it is old and worn and needs to be replaced? If it is slipping it will likely be slipping on other pulleys also.
2. You have allowed the power steering fluid to run low and the PS pump is starved and is sucking air. Running the fluid low will damage the PS pump and the steering rack. Low fluid in the PS reservoir is normally a sign of a fluid leak in the system. A leak could be on a system hose, in the PS pump or in the steering rack.
3. The PS pump may have failed, hence cannot produce the required pressure in the PS system, and needs to be replaced.
It means the power steering pump is no longer operating and so providing the required power assistance.
You either have a power steering fluid leak in the system and much of the fluid has been lost or the power steering pump itself has failed. You should not try and drive the car when you have this problem because the steering will be far too heavy to drive safely and because if a fluid leak has run the pump nearly dry you will cause damage to the PS pump.
The first thing to do is check the power steering fluid reservoir in the engine compartment. If it is low or empty you have a leak in the system. You can refill the system with new fluid but it will continue to leak until the leak is addressed and you will have to constantly add new PS fluid. In the case of a major leak the car will not be driveable as the PS fluid will be lost very rapidly. Without fluid you will quickly ruin the pump and you will also have no power assistance in your steering.
hi. if the fluid level is ok, then there is probably not a leak in the system. check the tyre pressures are correct as underinflated tyres can make the steering heavy, as well as increasing tyre wear. if the tyre pressures and fluid levels are ok then check the belt driving the power steering pump is ok. other problems include a bad power steering pump. a faulty rack, or siezed joints on the struts.
sounds like your power steering is failing, get it checked at a garage asap, steering is important when going fast :), probably needs steering wheel taken apart and power steering components checked for wear/damage.
Power steering does not seem to have any assist when at a stop.
1. The power steering assist is speed dependent and should be quite easy when stopped/low speeds. This is controlled by a solenoid on the side of the steering gear box.
2. Check for faults in all control modules. The general module is what controls current flow through the solenoid. Clear all faults and see if power steering operation is normal.
3. At the servo, check for power and ground from the general module. If none present, check wiring back to general module connector X254, pin 9, Black/White and pin 11, Black/Red.
4. Replace solenoid as necessary.
5. Disconnecting the solenoid will remove the variable assist function, but the steering system should still have considerable assist. If it does not with the solenoid disconnected, consider hydraulic faults as the most likely cause. A failed power steering pump is much more likely than the steering gear.

I know that there is 1 serpentine belt that runs all (incl. the PS pump) on the 3.8 liter. So if that belt
was missing, you would also be over heating, have no alternator charging, no ac (if equipped) as well as have no PS. If you see any belt at all (on the passenger side), then you are ok. The PS fluid resevoir is near the top and easily found. It has writing on the cap which also has a built in dipstick. Check the fluid level in the resevoir and fill it if nec. Are you hearing noises from the PS system with the fluids full? If so, you might need a new pump. Check for leaks too if the fluid was low, you might have a leaking hose or PS rack (hope not on the rack though $$)
Unfortunately Discoveries will always eventually leak some fluid, People who say theirs do not leak have just not found the problem yet. I just traded a 2003 for a new vehicle. First the power steering can and does leak but since the fluid capacity is not that much, if you have a continous leak and the power steering still works it is probably not the leak you need to address. also the plastic splash guard makes it difficult to identify leaks easily. My 2003 discovery was leaking for a while the leak was from the auto trans cooler. Check the leak colour, white paper under car, red fluid will be the trans fluid, The power steering fluid in the car is a special fluid (not trans fluid) if the correct fluid would be a greenish colour. Other than this oil leaks can be plentiful.
