W163 Mercedes ML HVAC Electronic Motor Levers / Arms Replacement Kit (2002 – 2005)

Are you hearing the dreaded whirling noise coming from under your ML’s dashboard? You may be experiencing failed HVAC Electronic Motor Lever / Arms which adjust the multiple vents to direct airflow where intended. This is a common failure on the facelift W163 and can be fixed in an hour or so if you’re willing to dig under the dashboard in the drivers footwell!

This kit included 3 of the W163 HVAC Electronic Motor Levers / Arms. Each of the three HVAC motors must be unscrewed from their mountings, after which the levers / arms slide off, and the new ones can be installed! Easy as that!

Our Replacement Levers / Arms are designed using CAD technology and are manufactured utilizing HP’s Multi-Jet Fusion (MJF) process. This method offers significant quality improvements over other 3D printing techniques such as Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM). The material from which the covers are printed is Nylon PA12 with a 40% glass bead mix, ensuring great dimensional stability, durability, and longevity. Then we install a heat-insert to enable the metal pin to be installed to the levers / arms.

NOTE: This kit does not include the electronic HVAC motors onto which the arms are placed. Rarely do motors need to be replaced but if yours are broken, the part number for them is 163-820-09-08 (~$150).
