How does this motor match my vehicle’s original equipment?

The 742-142 is built to mirror the form, fit and function of the OEM lift motor for the specific years and models it covers.

Using the vehicle lookup ensures you pick the correct application before ordering.

It offers the same basic operating characteristics as dealer units but at a lower purchase cost, and it’s supported by engineering and quality inspections in the United States. For many owners, that result is restored window operation without the higher service parts price often charged by dealerships.

How difficult is installation and what should I prepare for?

Installation is intended to be straightforward for someone comfortable with basic vehicle trim removal and electrical connections. The motor is manufactured to integrate with the original wiring and mounts, so most installations simply reverse the removal steps. Have basic hand tools ready and verify the part number against your vehicle before starting.

What quality assurances or limitations should I know about?

Dorman inspects and engineers replacement parts to meet aftermarket expectations, but like all mechanical components, lifespan depends on vehicle conditions and usage. This motor is a mechanical/electrical replacement and does not alter the original regulator design. Confirm fitment for your exact model and trim to avoid returns.

• Backed by Dorman engineering and quality control processes
• Intended as a direct-fit replacement, not an upgrade to regulator design
• Performance can depend on regulator condition and wiring health
