Hyundai part number 95470D3100 is the Control Module Assembly-Power Tail Gate, LH.  

This means it's the control module for the power liftgate (also known as a power tailgate) on the driver's side of a Hyundai vehicle.

Here's what this part does:

• Controls the operation of the power liftgate: This includes opening and closing the liftgate automatically, often with the push of a button on the key fob, inside the car, or on the liftgate itself.  
• Manages safety features: It likely integrates with sensors to prevent the liftgate from closing on obstructions and may include features like pinch protection.
• Communicates with other vehicle systems: This module communicates with the car's computer system to ensure proper operation and may interact with the security system.

Essentially, this part is the electronic brain that makes the power liftgate function.

Important Notes:

• This part is specific to vehicles with a power liftgate option.
• The exact compatibility might vary slightly depending on the model year and trim level of the Hyundai. Always double-check fitment with a Hyundai parts specialist or by using a vehicle parts database.
