Steering my cars steering light turns on then the wheel gets hard. I've checked the power steering fluid and it has plenty its a 2006 chevy cavalier

if it is electric power steering pump and hard to steer then the motor for the pump is not operational
check relays and fuses

Sounds like a broken serpentine belt.

ck. p.s hoses 4 leakage fill pump have someone turn wheel back & forth look 4 leak

YOU HAVE AIR IN THE POWER STEERING SYSTEM.YOU NEED TO BLEED POWER STEERING PUMP FIRST BEFORE DRIVING VECHICLE.CHECK POWER STEERING FLUID LEVEL ADD MORE POWER STEERING UNTIL REACH FULL COLD MARK..RAISE VECHICLE FRONT WHEELS OFF THE GROUND.START ENGINE LET IT IDLE WHILE TURNING STEERING WHEEL LEFT TO RIGHT NON STOP DONT LOCK OR STOP STEERING WHEEL KEEP TURNING IT SEVERAL TIMES CHECK POWER STEERING FLUID IF LOW ADD UNTIL YOU GET COLD MARK ON DIP STICK DONT OVER FILL POWER STEERING PUMP BLOW A SEAL.IF POWER STEERING FLUID LOOK TAN COLOR SYSTEM FULL OF AIR.TURN OFF IGNITION LET CAR SET FOR A WHILE CHECK FLUID LEVEL.IF STEERING WHEEL FEEL STIFF HARD TURNING DONT DRIVE CAR UNTIL YOU HAVE NORMAL STEERING.IF STILL HAVE AIR IN SYSTEM BLEED SYSTEM UNTIL AIR IS OUT.

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.

Hi. If steering fluid is ok I'd look at pump.

the most probable cause is the rack and pinion steering system. check for leaks in system, make sure if its full of power steering fluid.. if all checks ok, then its in the rack and pinion. that causes binding. I had a car that did the samething on turns. it was the rack doing this.

Turn car off - Remove power steering cap, and turn streering wheel hard right or left and fluid should pour out (cover surroundings with rags.) If so, check your power steering pump.

The power steering is electric on that car. It has a electric motor on the column, and a control module. There are several causes that could be the problem. You need to have it scanned to get a better idea of what to do. If you can give me the codes you get then I will be glad to advise you on what's best. Good Luck

have the power steering pump checked, sounds like low pressure, a quick test drive by a front end tech will decide if the pump is the issue or the rack and pinion steering unit is the cause..
