DESCRIPTION
Keep your Peterbilt mirrors responsive with the ROADWEST Door Mirror Power Motor, designed as an OE-style replacement for power mirrors on Peterbilt 325, 330, 335, 337, 340, 348, 365, 367, 379, 382, 384, 385, 386, 387, 388 and 389 trucks.
This driver/left side mirror motor installs inside the door mirror assembly and controls the movement of the mirror glass. If the original motor has failed, become noisy, or no longer responds to the switch, this replacement allows you to restore full electric adjustment without buying a complete new mirror.
Built as an OE replacement assembly, the ROADWEST motor aligns with the factory mounting points and electrical connector for compatible Peterbilt models equipped with power-only mirrors. When correctly matched by model and configuration, it can typically be installed using the existing bracket and wiring, minimizing downtime for your truck.
The vehicle-specific fit for Peterbilt 3-series and 300/300+ models (325 through 389) supports accurate and stable mirror positioning at highway speeds. With a functioning power mirror motor, drivers can quickly adjust the glass to compensate for different trailer widths, loads, and seat positions, improving comfort and safety.
This Peterbilt door mirror power motor is DOT approved and manufactured as a new aftermarket part, not used or remanufactured. It is suitable for trucks where the original door mirror was equipped with an electric adjustment motor.
If you are unsure whether this motor fits your specific Peterbilt 389, 379, 365, 367 or other listed model, the support team for ROADWEST and ROADWEST can help confirm compatibility before you place an order.
