* Power Steering Pump Failure: The power steering pump assists in turning the steering wheel. If it fails, the steering becomes much heavier (requiring significantly more effort to turn). A failing pump can also draw excessive current, triggering the battery light.
* Alternator Problems: The alternator recharges the battery. If the alternator is failing, it won't adequately charge the battery. This will cause the battery light to illuminate, and eventually, the low battery voltage could affect electrically-powered components like the power steering pump, making the steering heavy.
* Low Battery Voltage: A completely discharged or very weak battery can also cause both symptoms. The power steering pump might not receive enough voltage to function correctly, leading to heavy steering, and the low voltage will trigger the battery light.
* Belt Issues: While less likely to cause *both* symptoms simultaneously, a broken or slipping serpentine belt (which drives the alternator and power steering pump) could cause problems. A broken belt would immediately stop the power steering and the alternator, leading to a dead battery and heavy steering. A slipping belt might initially cause only intermittent issues.
What to do:
1. Don't drive the car extensively. Continuing to drive could worsen the problem and potentially damage other components.
2. Check the battery terminals: Make sure they're clean and tightly secured.
3. Have it checked by a mechanic immediately. Accurate diagnosis requires a professional inspection to determine the root cause (failing alternator, power steering pump, battery, or belt). Ignoring the problem could lead to more costly repairs or even a breakdown.
In short, the combination of heavy steering and the battery light strongly points to an electrical issue affecting a vital component, most likely the power steering pump or the alternator. Professional help is needed to resolve the issue safely and effectively.
