• Improved design uses higher strength nylon gears coated with superior lubricant, heavier duty motors and redesigned circuit boards to prevent burnouts
• Precision replacements that mount in the existing position without modification
• Plug and play and do not require any programming
• Exceeds the design of OEM motors
• Life cycle tested in excess of 10 thousand hours
• Provide a more durable service life in the HVAC temperature control system

Tip: always make sure that the electrical connections are clean and free of dirt or moisture before connecting together. This will ensure that the new product will work correctly.

• Use a multimeter tool to diagnose the system. First, check the ground. When the rear system is covered in plastic, and hard to get to, grounding issues from previous repairs may be the problem.
• Check the voltage supplied by the control head to the blend door. Refer to the manufacturer's wiring diagram. The wires should carry 12V. If the voltage is less than 12V, the control head may be the issue rather than the actuator motor.
• Check the door. Is it stuck? Debris may have found its way into the blend door and wedged itself in between the door and housing, causing it to stick and burn out the motor.

Which Actuator Do You Need?

RECIRCULATION

Controls the intake of air into the system, either bringing outside air in or using inside air in recirculation.

BLEND

Controls the temperature of the air flowing from the vents by mixing hot and cold air from the heater core and the evaporator core.

MODE

Controls which vents have air flow, i.e. Floor, Panel or Front, Defrost, or any combination of those.

Diagram:

The term "Main" refers to the air flow control of the Front Vents. The term "Auxiliary" refers to the air flow control of the Rear Vents.
