Air Conditioning Issue
Good morning all -
Hoping that someone can lend their experience for my 2nd generation MDX (2007). The problem is very similar to what others have posted before, but the solution must be different. In summary, the air conditioning blows at three distinctly different temperatures, rear (cold, ~63 degrees), passenger front (cool, ~73 degrees, and driver front (ambient, ~93 degrees).
I, like others, thought it might be a Freon problem. I checked it last night with the manifold gauges (and added a touch extra) to get the suction side pressure to ~47psi and the high port was ~205psi. That appeared to be within the acceptable limits per the service manual for a 95 degree, 80% humidity day.
I’ve also taken off the drivers side mix door. When changing the temperature in the car, it appeared to have full range of motion. Also, when I adjusted the door positions by hand (without the servo), I was unable to get cold air then either.
Starting to hit a wall, so I’ll take any advice that y’all have. TIA
