Intermittent a/c issue

I have a 2018 Toyota Prius and yesterday the A/C started acting funny. The passenger side vents won’t blow any air at all but all other vents work. Only the floor vent works on the passenger regardless of directional setting. Also, the air would only blow cold air even when I adjusted the temp all the way to high. I googled and recommended that I disconnect the battery for a few minutes to see if it resets the passenger side actuator. I tried that and got my heat back but now it blows hot air when the engine is running but when I’m on the hybrid battery and engine is off it goes back cold, but still no passenger side air. Driver side, and floors and defrost work fine. Coolant levels are fine. No check engine or warning lights. A/C line is cold. I looked in the glove compartment and it does look like the passenger acuator isn’t working when I’m cycling through the settings. Cabin air filter and hybrid battery filter are fine as I swapped cabin filter for a new one a few months ago and cleaned hybrid battery filter at that time as well. I did order a servo assembly acuator for the passenger side in the event it is that. Just trying to keep from taking to dealership.

Any ideas?
