Hey everyone on my 2015 is350 when i turn the A/C on full fan speed and temp control at LO? the passenger front vents are noticeably warmer than the drivers side vents.

has anyone experienced this before? Owning a bmw previously they had a similar issue with blend doors i wonder if this is similar? Or low AC refrigerant?

thanks!

 

Low refrigerant for sure but they should check for leaks as well for the compressor kicking on.

 

You may have the issue covered by a service campaign, see this thread (which links to another informative thread):
