Try To Slowly Move The Car Towards The Kerb

You should try to direct or steer your car to the shoulder of the road. You’ll need to observe the coming traffic on the road and control the vehicle away from it.

Bring It to A Stop

You should gradually slow down the car until it stops. Remember to brake lightly while you are driving and then eventually park the car on the shoulder of the road.

What Causes Power Steering To Not Work At Idle?

There can be plenty of culprits for a power steering not to work at idle. The primary reason or culprit for it is a failure of the power steering pump. Some other reasons that might contribute to this situation are

No power steering fluid

If your vehicle doesn’t have any power steering fluid, then the power steering will not work even when you keep it idle. Usually, there is a leak in the system somewhere for the power steering fluid to not be in the pump. 

You’ll have to identify and patch that leakage. You can also check the valves, hoses, and hydraulic pumps to ensure no more leakage. 

Faulty or damaged hydraulic pump

Damage to the hydraulic pump can also stop the power steering from working. Less power steering fluid in the vehicle can also damage the hydraulic pump. You can identify damage on your hydraulic pump as it will start making noises. 

As the damage to the hydraulic pump gets older, you’ll experience the steering assist being weaker. Once the pump stops working, you’ll get zero steering assist.

Broken serpentine belt

The hydraulic pump with the engine works or spins because of a serpentine belt. A crankshaft pulley then drives this belt. If this belt breaks or snaps, the hydraulic pump will stop working, and you will get no steering assist. The pump will not be able to receive the supply of power steering fluid. 

Older electric parts

If the electric components in your vehicle are old and worn out, they can also make the hydraulic pump faulty. Power steering systems have a torque sensor, electric motor, and other components. 

If any of these components have a short circuit or their fuse is not working, the entire system will shut down.
