Review on 🔧 HVAC Air Door Actuator - Compatible with Chevrolet Impala 2004-2013 - Replaces Multiple Part Numbers - Heater Temperature Blend Door Actuator by Jeremy Choi

GM OEM actuators were and still are made in China, cheap plastic gears guaranteed to break a tooth or two on one or both drive wheels Impala 2006 year with only 68,000 miles on it. I have swapped both the passenger heater actuator and the mixed door actuator twice. Installation is a challenge, especially with the mixed door operator. . Interestingly, there are niche suppliers that only sell gears. They are much stronger and made of nylon material. So take a look at the drive you are about to replace, carefully lifting up all the little clips to find which gear tooth is broken. replace them with nylon gears, or even if you bought the whole drive disassemble it and liberally lubricate the teeth of all gears with silicone grease. This will take longer. Inadequate lubrication leads to premature gear failure.
