What is the reason for the steering wheel not moving in a Mercedes-Benz power steering failure?

[OLogan]

Mercedes-Benz car power steering failure causes the steering wheel not to move for the following reasons: 1. Hydraulic power steering: Check if the power steering fluid is insufficient, and there is no oil leakage. If the oil is low, it needs to be replenished to the normal range. If the oil level is normal, check if the power pump belt is too loose. If it is too loose, the belt needs to be tightened. Also, check if the oil is too dirty due to poor mobility, generally requiring replacement every 2 years or 60,000 kilometers. 2. Electronic power steering: Check if the fuse is blown, and if there are any open circuits or short circuits in the wiring. 3. Check tire pressure: Air leakage can also cause the steering to be heavy or unmovable, and inflation is required.
