Interesting info regarding the potential source for many climate control problems, nice work.
Last summer this site collected a lot of owner complaints about insufficient cooling air and weird/incorrect climate control logic. My AC is certainly not “ice cold” like my other vehicles, and just yesterday I was commenting to my wife about how the climate system seems to take inappropriate actions based on ambient vs commanded temps.... I wonder if the blend door problem you are discussing is related?
I wish there was a way for
@RamCares to point Ram engineers at a post like yours above
@KcRay to briefly review how shutting off a line like you did drastically improved the AC performance. Maybe it could provide them a direct path to fixing a problem that we’ve heard exists in many trucks, as evidenced by the complaints and service calls last summer.
I suspect these climate control complaints and service calls will increase again soon and Ram will be hearing a lot about it... would be great to help them get a leg up on a fix. But how do you get their ear? Must it be through a star case?
