Cab Heater Mix Damper Servo Motor DZ97189585302 Corrugated Protective Wiring Harness Temperature Adjustment Actuator

Cab Heater Mix Damper Servo Motor DZ97189585302 Corrugated Protective Wiring Harness Temperature Adjustment Actuator

Product Description

This air mix damper actuator marked OE number DZ97189585302 is the core servo control component of heavy truck cab heating and air conditioning system. Installed inside the HVAC evaporator housing, it receives electronic temperature adjustment signals from the cab control panel to drive the internal gear set and swing the blend air flap. By adjusting the opening ratio of hot air and cold air passages, it accurately mixes cold and warm airflow to realize stepless regulation of cabin outlet temperature, solving single hot/cold air output failure caused by aging or stuck original motor during vehicle operation. The complete pre-assembled wire harness and matching plug realize direct plug-and-play replacement without wire cutting.

Key Product Advantages

• High-strength sealed ABS plastic housing, dust-proof and moisture-proof internal gear structure, adapting to high temperature and humid environment inside the HVAC box without gear jamming.
• Multi-color core wire wrapped by full-length corrugated plastic sleeve, effectively resisting abrasion, high-temperature baking and wire fracture from long-term cab vibration.
• Standard blue multi-pin waterproof connector, perfect matching with the original vehicle HVAC wiring harness, stable signal transmission without poor contact.
• Precision reduction gear group inside the motor, smooth rotation with low noise, accurate angle positioning of the air mixing flap to achieve stable temperature control effect.
• Standard reserved mounting screw holes consistent with the original air conditioner housing, one-step bolt fixing during maintenance replacement without structural modification.
