Navigator AC blows fine on the driver side but weak on the passenger side.

Kind of a strange one and I’m hoping someone here has run into the same thing because I’ve been scratching my head over it for a couple weeks now, my Navigator has dual zone climate control, and up until recently both sides worked exactly as expected, but lately the passenger side has been noticeably weaker than the driver side even when both zones are set to the exact same temperature and fan speed, it’s not like the passenger side is blowing warm air or anything dramatic like that, it’s just clearly less forceful and slightly less cold compared to what’s coming out on my side, my wife actually pointed it out first since she’s usually the one sitting there, she mentioned feeling like the air just wasn’t hitting her the same way it used to, and once she said something I started paying attention and realized she was completely right, at first I figured maybe it was just a vent that needed adjusting or something simple like that, checked the vent positions, made sure nothing was closed or blocked, but the issue persisted even with everything set correctly, which told me this probably isn’t just a simple mechanical vent issue and more likely something related to the actual dual zone system itself, maybe a blend door not fully opening on that side, or possibly an actuator that’s not functioning correctly anymore, since these dual zone systems rely on individual doors and motors to control temperature and airflow independently for each side rather than just one shared system for the whole cabin, did a bit of reading last night trying to understand this better and came across some information specifically about this kind of asymmetric airflow issue in larger SUVs with dual zone setups, and it mentioned that this pattern where one side underperforms while the other works completely normally is actually a fairly recognizable symptom that Leading Lincoln AC repair Sharjah services deal with somewhat regularly, usually pointing toward exactly what I suspected, a blend door actuator not moving properly on the affected side, rather than anything wrong with the compressor or overall refrigerant levels since obviously if it were a refrigerant issue both sides would be affected equally rather than just one, which honestly matched everything I was noticing pretty well, still haven’t taken it in yet since it’s more of an annoyance than an emergency at this point given that at least one side is working perfectly fine, but my wife has made it clear she’d like this fixed sooner rather than later since she’s the one dealing with the weaker airflow most of the time during longer drives, has anyone else had this specific issue with uneven airflow between zones on a larger SUV, and if so did it end up being the actuator like I’m suspecting or was there something else going on that I haven’t considered yet, curious also whether this tends to be a quick straightforward fix once diagnosed or if actuator replacements on these bigger vehicles tend to be more involved than people expect going in.
