• Whether DIY is recommended or professional installation is better:
• DIY is recommended for most people. It's a straightforward job. If you're not comfortable working with electrical components, professional installation is a good idea.

• Compare: Used OEM, New Aftermarket

• Used OEM: Best value - genuine factory parts, tested and inspected, at significantly lower prices. These are original parts made by the vehicle manufacturer. They've been removed from used vehicles and checked to ensure they work.

• New Aftermarket: Brand new third-party parts built to OE specs. These are new parts made by companies other than the original vehicle manufacturer. They are designed to fit and function like the original part.

• Parts commonly replaced or checked at the same time:
• Window motor
• Window regulator
• Door lock actuator
