Which power steering system does your vehicle have ? EPS - electric power steering or hydraulic power steering . Do you have a EPS light lit on the instrument cluster ?
Power Steering System Description and Operation (EPS)
The power steering system reduces the amount of effort needed to steer the vehicle. The system uses the powertrain control module (PCM), body control module (BCM), power steering control module (PSCM), discrete battery voltage supply circuit, steering shaft torque sensor, steering wheel position sensor, power steering motor, driver information center (DIC), and the serial data circuit to perform the system functions. The PSCM and the power steering motor are serviced as an assembly and are serviced separately from the steering column assembly. The steering shaft torque sensor and the steering wheel position sensor are not serviced separately from each other or from the steering column assembly. The steering column assembly does not include the power steering motor and module assembly.
Power Steering System Description and Operation (HPS)
The hydraulic power steering pump is a constant displacement vane-type pump that provides hydraulic pressure and flow for the power steering gear. The hydraulic power steering pumps are either belt-driven or direct-drive, cam-driven.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine
The 2 basic types of power steering gears are listed below:
• A recirculating ball system
• A rack and pinion system
In the recirculating ball system, a worm gear converts steering wheel movement to movement of a sector shaft. A pitman arm attached to the bottom of the sector shaft actually moves one tie rod and an intermediate rod move the other tie rod.
In the rack and pinion system, the rack and the pinion are the 2 components that convert steering wheel rotation to lateral movement. The steering shaft is attached to the pinion in the steering gear. The pinion rotates with the steering wheel. Gear teeth on the pinion mesh with the gear teeth on the rack. The rotating pinion moves the rack from side to side. The lateral action of the rack pushes and pulls the tie rods in order to change the direction of the vehicle's front wheels.
The power steering pressure hose connects the power steering pump union fitting to the power steering gear and allows pressurized power steering fluid to flow from the pump to the gear.
The power steering return hose returns fluid from the power steering gear back to the power steering fluid reservoir. The power steering return line may contain an integral fin-type or line-type power steering fluid cooler.
In a typical power steering system, a pump generates hydraulic pressure, causing fluid to flow, via the pressure hose, to the steering gear valve assembly. The steering gear valve assembly regulates the incoming fluid to the right and left chambers in order to assist in right and left turns.
Turning the steering wheel activates the valve assembly, which applies greater fluid pressure and flow to one side of the steering gear piston, and lower pressure and flow to the other side of the piston. The pressure assists the movement of the gear piston. Tie rods transfer this force to the front wheels, which turn the vehicle right or left.

SOURCE: Where do i add power steering fluid to a 2005
There is no power steering fluid in the system.A 2005 Malibu is electronic steering.If you lose assist you may have to replace the steering column.You may also have an intermediate shaft that is binding.The I-shaft connects your steering column to the steering gear.There is a universal joint in the shaft that may be stiff or seized.
SOURCE: My Power Steering fluid is low, I want to add
they have no place to fill power steering fluid it uses brake fluid and power steering fluid for both systems the electric power steering fluid system is joke if its broke you have to spend 1200$ PLUS TO FIX PROBLEM I HERE LOTS OF PEOPLE HAVING PROBLEM WITH IT WORKING ONE MINUTE NOT THE NEXT UNTIL IT KILLS SOMEONE IT WONT BE FIXED IT SHOULD BE RECALLED AND THENTHE SYSTEM SHOULD NEVER BE USED AGAIN CHEVY KNOWS OF PROBLEM BUT WONT FIX PROBLEM BECAUSE ITS TOO EXPENSIVE SOUNDS JUST LIKE TOYOTA UNTIL THE COST OF LAWSUITS OUTWEIGH THE PAYOUT ON CLAIMS THEY WONT DO NOTHING WE PEOPLE NEED TO FILE SUIT SO PEOPLE DONT DIE BECAUSE OF THE GREED OF BIG COMPANIES TURNING THERE NOSE UP UNTIL SOMETHING OR SOMEONE CHALLENGES THEM IM NOT ASKING NOTHING MORE BUT FIX THE PROBLEM FREE NO MORE NO LESS AND BYE THE WAY EVERYONE IS COMPLAING OF CLUNKING SOUNDS WHEN TURNING DUE TO ANOTHER PROBLEM WITH STEERING SYSTEM NO WONDER PEOPLE DONT BUY AMERICAN CARS ANYMORE
SOURCE: How do you fix the
a few possibilities.
Low power steering fluid. check for correct amount on pump filler measureing guage.
Loose power steering belt. check to see if the belt slips over the power steering pulley while trying to turn the steering wheel. may need an assistant.
last, but most expensive. Rack and pinion steering bar is defective and needs replacing.
SOURCE: 2006 Chevy Malibu - the
Your 06 Malibu has electric assist power steering. There is no reservoir, or pump for that matter. A previous problem of this sort was on the website a couple of weeks ago, and someone had mentioned that there was a recall for this problem. Call your Chevrolet dealer and inquire.

I have EPS and the EPS light is lit on the instrument cluster.
Can anybody give me advice on this situation please.
