Hi.
My 2010 mustang convertible base. 95k miles.
The driver side vents get noticeably warmer than the passenger side. Even the two center vents. Had the installing shop check, but claim temp is the same. Seems some what intermittent, possibly based on outdoors (Arizona). Any ideas ?
thanks in advance for any help.

I have the same issue with my 2007 v6. Took to a shop they said the a/c control arm was bad and not letting it flow properly. Idk tho cause sometimes its as cold as the other 3.
