Has anyone replaced the driver side blend door actuator for either the 2011-2013 Infiniti M's or 2015-2019 Infiniti Q70's? I'm having a hard time finding where it is exactly online or in the service manuals. I see plenty of info for the Q50 but not q70. Thanks!

See page HAC-130 here:

All 5 of the servos call for removing the whole HVAC Unit. I don't know if that's right, you might be able to just remove the dashpad, but it looks like a big job no matter how you cut it.

Okay so I looked at all three actuators on the left side and they seem to be actuating fine. The primary actuator on the left that actuates between heating and cooling is thankfully accessible from the underside.

Im starting to think maybe its a AC charging issue? The air blowing is not necessarily hot, it is just not as equally cold as the right side, which is truthfully not even that cold either. THe heater works as intended for both the left and right side of the AC vents

I only just started looking to this BTW becdause the car has been sitting for nearly 3 months due to being away from work.

The driver side on most Nissan products will get warm first if the A/C is undercharged. So your surmise may well be correct.

This ended up being in the issue, charged up the AC and now it blows cold AC, thanks for the guidance help Vstar! Now I have to add the dye in the system to figure out where it's leaking from.
