So, as per the title, the air con is blowing ambient temperature on the drivers side, but passenger and rear (4 zone) are nice and cold. I’m thinking it doesn’t need a re-gas given it’s cold on the other outlets, which led me to look at blend motors following a search on here.

Tried checking the positioning of the flap using the gap tool, but it just came back n/a, so I’ve taken the panel off as per this thread: https://www.fullfatrr.com/forum/topic48139...lend+motor

But mine, because it’s a 2011 model and/or because it’s 4 zone doesn’t have that blend motor, certainly not there anyway. I now know why the gap tool refused to give a reading!

So, any ideas from the collective?

Just to follow up on this, the warm air started coming through front left as well, and then shortly after that, rear left. With cold air only coming through rear right, I decided it was time for a re-gas. Just about to take it in when some idiot decided to drive into me.

Got the car back this week and first job was the re-gas. Pleased to report that everything is back to icy cold. Just as well given the weather!

Having the same problem with mine, thought it was the blend motor but will follow your advice and get the regas done and hope that cures it.
