My cab/outside air recirculation blend door actuator started sounding like a little machine gun going off every time It wants to move so I went on the mopar parts diagram and ordered a Oem mopar actuator by the part number it gives for that actuator on that door now when I received the actuator it has a sticker on it saying Single zone Defrost Actuator. do not use in dual zone or any other locations . ??
does that mean it only to be used on the defrost blend door ?? or am I miss understanding it ??
why ? is there something calibrated on it because on the Mopar parts diagram every Acuator is the same part number and shows this part number for the one I need and is the only Oem part number I can find for this so why I there that sticker on it ??
Is there something I don't know because I can't find much info on it or why.
I have AlfaOBD and have done a lot with it and am familiar with how to use it.
My truck is a 2017 Ram 2500 with single zone with the 8.4 Uconnect and auto climate.

I can't say for sure but I would guess its behind your glove box. You can open it so that it swings down out of the way and its behind there. At least in all of the cars I've seen.

Am I missing something? This is the 4th Gen section. You asking for a 5th Gen blend door location.
