Yet another issue has arisen.

As the title states, only the passenger side blows cold air. Freon levels are fine. I replaced the driver side blend door actuator (pain in the a**) and I'm 99% sure I calibrated it correctly, but no dice. I really need this fixed soon, this awful NC humidity is hot!!

 

Curios if you get this resolved mine is doing the same thing.

 

Did you replace your actuator too? I turned the key to on and played around with the driver side and I could hear the actuator spinning so I know that's working. I have no idea what the issue could be.

 

Mine is not replaced but I am confident as well that it is not the problem.

 

How did you check the levels for the freon? Because those are the 2 most common problems when this occurs.

 

I used the gauge that came with the recharge kit I bought a few months ago. Inaccurate?

 

Yes. Recharge kits don't vacuum fill like these systems need. There could be air in the system creating false pressure readings, and they also contain stop-leak sometimes which can plug up expensive parts.

I would let a proper shop diagnose the system pressure, usually they will do it for free/cheap.

 

Hi,
Just wondering if the freon or actuator turned out to be the culpret. My 2006 Monte has the exact same problem. I've already replaced the actuators on the pasenger side. I don't want to tackle the driver side unless I really need to. I heard it can be bear.
Thanks,

Sorry sir, I sold that car some time ago, a month or so after that problem appeared. If I had dug deeper into diagnosing the problem I believe it was a freon leak combined with a very low level.

 

if the car is blowing cold air out one side and not the other, then its not a Freon issue. if Freon was the problem it wouldn't run the compressor and you wouldn't have cold air out either side. the actuator motor on the driver side is a bit more of a pain than the passenger side but its not brain surgery either. just use some 1/4 inch drive extensions and maybe a 5.5mm swivel socket makes it much less difficult.
