Hi, I have a 2014 RDX and I am having an issue where the AC blows cold on passengers side and tepid on drivers side. Could this be an issue fixed with freon? Or is that unlikely?

 

Doubtful. Most likely a problem with the ducting, probably the dampers that direct the air to the various vents. Might check your cabin air filter but that's probably not it either.

 

Believe it or not, my Father's Buick LeSabre has this same issue from time to time. I thought it was the dampers as well. Reset system and all to no avail. Guess what, low on Freon. Don't ask me how it can still blow cold on one side and not the other. But it does/did, and a can of Freon fixed it. Just added some leak seal for the second time now. Good luck

 

Was curious if you fixed your AC issue? I have the same issue, AC blows cold on passenger side and warm on drivers side. I have read I needed to check refrigerant and the air vent motor module.
