21654870 mirror actuator – Description

21654870 mirror actuator is a control unit used in the outside mirror system to support mirror movement and stable positioning during daily operation. OE reference: 21654870. It is suitable for trucks compatible with VOLVO FH (EU, 2005) and compatible with VOLVO FM (EU, 2005), where the mounting configuration matches the specified OE reference.

A correctly functioning actuator helps maintain consistent mirror adjustment, improving visibility and reducing the need for repeated manual re-alignment after vibration or long-haul use. The housing and connection points are designed for commercial-vehicle service conditions, supporting dependable seating and practical replacement during workshop maintenance.

Replacement is commonly considered when mirror adjustment becomes intermittent, movement is slow or uneven, or the mirror does not hold position under vibration. During installation, compare connector type and fixing points, then secure the unit evenly to avoid stress on the mirror assembly and wiring.
