Direct-fit HVAC blend door actuator

This actuator replaces the original blend door motor on a wide range of GM vehicles including Chevrolet Silverado 1500 2004, Cadillac Seville 1998-2004 and Oldsmobile Cutlass 1995-1996. It uses the OE reference numbers 16163982, 89018365 and 604-106 among others. The five-pin connector and three mounting holes match the factory layout exactly.

Fixes erratic temperature control

When the original actuator fails the vents may blow only hot or only cold air, or the mode may stick on defrost. Swapping in this unit restores proper temperature blending and recirculation control without dealer programming. The repair is worthwhile whenever the HVAC system no longer responds to the dashboard dials.

Mounts with existing hardware

The black metal-and-plastic housing measures 9.5 by 7.5 by 2.8 centimetres and fits the original bracket using the 5mm, 7mm and 8mm hole pattern. No harness adapters or additional brackets are required. Buyers needing a dual-zone calibration procedure or a different pin count should verify their specific vehicle configuration first.

Questions about this item

Will the 5 mm, 7 mm and 8 mm mounting holes line up with my 2004 Silverado 1500?

Yes — the actuator has hole diameters of 5 mm, 7 mm and 8 mm that match the factory mounting points on the 2004 Chevrolet Silverado 1500.

Which step do people skip when swapping the 5-pin blend-door actuator?

After bolting the new unit in place, reconnect the 5-pin connector and run the HVAC calibration cycle so the controller learns the new door end-stops.

How long before the plastic gear set inside this 16163982 actuator typically needs replacement?

The metal-and-plastic construction is rated for long service life; most owners only replace it if the gear teeth strip or the motor fails after many heat cycles.
