How does this regulator simplify installation if the motor is already present?

The product arrives with core mechanical components preassembled—slide rails, brackets, and cables—so the body shop or DIY mechanic can swap the unit into the door without fabricating parts or complex machining. It’s intended for full-machine installation directly onto the existing mounting points.

• Pre-installed rails and brackets reduce assembly time.
• Direct-mount geometry matches OE locating points for alignment.

• Packaged to protect moving components during shipping.

What should I check before purchasing and installing?

Verify your vehicle’s model year and door location—this is the right-side rear regulator only—and compare the replacement part numbers with any OEM references. If your door motor was damaged, ensure you order a compatible motor or select a motorized assembly instead.

• Confirm vehicle: right rear passenger-side (rear right) for listed E90/E91 models.
• Compare part numbers: 749-469, 51357140590, BM1551111 to your OEM reference.
• If the electric motor is faulty, plan to replace or transfer the motor accordingly.

It’s ideal for anyone seeking an OE-sized mechanical assembly with preinstalled hardware and a one-year warranty for peace of mind during the repair.
