Genuine HELLA BEHR & MAHLE solid-state electronic blower regulator (Final Stage Unit / power transistor module), part number
5HL351321151. This is the original OEM fan speed control unit for BMW E65/E66/E67 7 Series digital automatic climate control system. It receives PWM signals from the climate ECU and delivers stepless variable speed control for the cabin blower motor. The thick cast aluminum heat sink rapidly dissipates heat and prevents overheating burnout, a common failure point on E65 chassis.
This single unit is fully interchangeable with five BMW factory OEM part revisions. It matches the original wiring connector and mounting hole layout perfectly for direct plug-and-play replacement without wire cutting or modification.
