Out of clue on driver seat natural wind, passenger seat cool wind, with MAX AC on

[Timber]

Issue:

Ford Edge 2011 SEL AWD model,

When AC on or MAX AC on, with air  recirculating on or off, the driver seat always has a natural wind, it's not cool, not hot, but natural wind,

while the passenger seat is working correctly with cool air.

The heater/hot air working OK for both driver and passenger seat.

 

I tried below solutions but nothing happened yet:

1. combination of AC power button and defrost button for 10 seconds, no click sound, no change

2. change the blend door actuator at driver side, no change

 

And I even sent the car to the Ford Dealer who sold it to me, and just got it back from them,

 they are saying the issue is from the inner temperature sensor and the condenser, which they suggest to be replaced at a cost of $1700.

I totally not agree with that diagnosis, because this is definitely not the cause of driver seat no cool air.

They kinda agreed with me but no further comments, looks like the technician there lack of skills to nail down the root cause.

 

Other fix/change happened before:

I fixed the AJAR issue at driver door via connect the wire to a bolt in driver door.

I doubt it has anything to do with this AC issue.

 

Any comments/thoughts/AC system diagram are welcome!

 

Thanks,

When I had my 2011 and the AC gas was low, the driver side would lose cooling while passenger side was ok. Once gas leaked more, both sides would lose cooling. So maybe that is also your issue, low AC gas.
