HVAC Blend door actuator

My 2005 Tacoma has started blowing warm air from all the vents EXCEPT the driver side door vent. With the AC on, there’s (what feels like) a 10°+ difference in the air temp coming out of the vents. Everything I’ve seen says probably Blend Door Actuator. My problem is, looking at ordering parts, there are 2 of them. One for the mode, one for the temp. I found a video showing one behind the glove compartment - which appears to be the mode actuator (he was having a clicking sound when selecting recirculate, but would go away when he had fresh air coming in).

Long way around to get to my question. My question is: where’s the second actuator located?

 

Here are the locations of the three actuators.

 

Before screwing with anything mechanical get the R134a charge checked. Cool at the drivers side and getting warmer towards the passenger side is one of the first signs of low R134A. Note: I had the same symptoms on my 2012 and had a leak on the high pressure hose.
