What's wrong?
The mirror control joystick switch on these 2019-2023 Byd RIDE buses is the small electrical control the driver uses to aim the outside rearview mirrors. It sends power through the mirror control circuit so the right and left mirrors move up, down, and side to side from the driver's area. A fuse in that circuit is supposed to interrupt current before the switch overheats.
In the affected switch module, the fuse rating does not give enough protection for the circuit. Byd traced reported mirror switch malfunctions and overheating at the switch base to the Safe Fleet mirror control switch module, then identified the remedy as a modified switch with a 1AMP protection fuse. The problem is in the switch protection, not in the basic bus mirror layout.
Byd is not aware of any warning that appears before the switch overheats or stops working. There is no warning sign before failure, so a driver first notices the problem when the mirror control switch malfunctions or feels overheated.
Who's affected?
The scope spans K-series and C10M buses from 2019-2023, all tied to the mirror control joystick switch and the same visibility and wiring components.
