Hi All, I had a loud clicking noise emanating from behind my glove box. I figured out that it was coming from an actuator. Everything I found on the internet said it was a blend door actuator so I ordered one for the passenger side before removing the old one. My car has dual climate control. Once I removed the old one, the new one was virtually identical except the actuator arm on the unit is about 2 times longer than the old one. The internet only discusses 2 actuators, one on the drivers side and one passenger side. My car has 2 on the passenger side, one on the left under the glove box and the one I removed which is on the left side of the box that contains the cabin filter. The old actuator has part number DENSO AW063700-8350. I cannot find any reference to this part # anywhere. Does anyone know what part this is and what replacement part will fit? Thank you.
