17 18 19 20 Honda CR-V Left Driver Side Master Window Switch 83591-TLA-A010-51

Description

This is a genuine OEM Honda Door Multiplex Control Unit (ECU), part number 83591-TLA-A010-51. This module is the central electronic controller for the driver’s side door on the 5th Generation Honda CR-V. It is a sophisticated "smart switch" that manages digital signals for the power windows, central locking system, and power side-view mirrors.

This unit is the factory-correct replacement for vehicles experiencing a total loss of window control, failure of the door lock buttons, or communication errors between the door and the Body Control Module (BCM). This module was carefully removed from a donor vehicle and has undergone a thorough visual inspection. The buttons are in excellent tactile condition and the electrical connector pins are clean and free of moisture or corrosion.

Installation Note

PRO TIP: After installation, you may need to perform a "Window Reset" to re-initialize the Auto Up/Down feature.
