Review on 🔧 High-Performance HVAC Heater Blend Door Actuator: Updated Version, Replaces# 604-970 27743ZP00A - Perfect Fit for 2004-2009 Nissan Quest, 2004-2015 Nissan Titan, 2007-2015 Nissan Armada, 2004-2010 Infiniti QX56 by Mark Clark

Purchased to fix the infamous faucet door click in the Nissan Titan that was interfering with the heater. I was able to successfully install it by removing the glove box and reaching to the top of the HVAC unit. It was quite difficult as it's so narrow and you basically work blind by feel. The only issue with this drive in my circumstances was that part of it is about an eighth of an inch longer than the OEM drive, so I had to trim the mounting plate a bit to make it fit. Holes for screws and everything fits perfectly. We took apart the old actuator to see what the problem was with these things and found that 2 teeth had snapped off a simple little plastic gear. Hopefully this "updated" version will last longer. So far it works great and finally have a working heater.
