* Power Steering Fluid: This is the most likely culprit. Cold weather thickens power steering fluid, making it harder to turn the wheel. Check your fluid level. If it's low, add the correct type of power steering fluid (consult your owner's manual). If the level is fine, the fluid might be old and degraded, requiring a flush and fill with fresh fluid.
* Power Steering Pump: A failing power steering pump may struggle to move the thickened fluid when cold. Listen for whining noises from the pump when turning the steering wheel, especially when cold. A failing pump will likely need to be replaced.
* Power Steering Rack and Pinion: Worn seals or internal components in the rack and pinion can cause stiffness, especially when cold. This is a more expensive repair and requires a professional diagnosis. You might hear knocking or clunking sounds from the steering when turning.
* Low Battery Voltage: A weak battery can sometimes cause insufficient power to the power steering pump, leading to difficulty turning. Check the battery voltage.
* Fluid Leaks: A leak in the power steering system will reduce the fluid level, exacerbating the problem in cold weather. Inspect the hoses, pump, and rack and pinion for any signs of leaks.
Troubleshooting Steps:
1. Check the power steering fluid level: This is the easiest and cheapest step. Add fluid if needed, using the correct type.
2. Listen for noises: Whining from the pump suggests pump failure. Knocking or clunking from the steering might indicate rack and pinion issues.
3. Check the battery voltage: Ensure your battery is providing adequate power.
4. Inspect for leaks: Carefully look for any signs of power steering fluid leaks.
5. Consider the age of the fluid: If the fluid is old, a flush and fill is recommended.
If the problem persists after checking the fluid level and adding fresh fluid, it's best to take your Dakota to a qualified mechanic for diagnosis. Ignoring the issue could lead to more extensive and costly repairs down the line. A mechanic can pinpoint the exact cause and recommend the appropriate solution.
