AC issues driver side only issue 07 ES350
Hi guys hope eveyrone is doing well on this sunday.
I was in las vegas last week and i always realized i had some issues where the ac would be a bit colder on the passenger side and the rear vents then on the driver side when im just sitting at traffic lights or stopped usualy wheni get moving it will get a bit colder and when on the higher it gets really nice ac cold. however i never noticed it blow look warm when stopped before untill i was in vegas this past week and it was 100 outside the only time it would get cold at all on the driver side was when moving
does anyone have any ideas they could give me that would be the cause of this
is it just that the freon might be low or do i have a issue with major ac components ?

I would check the freon 1st and see if it is at the right pressure. If it is OK then you might be having a problem with the mixing valve which directs the air flow to either side of the car and controls the AC vs. heat . If this is the case it would most likely be a dealer fix.

ok thank i will check this and see if its a freon issues can you tell me what the right pressure needed would be for the 07 ES350 ac unit ?
and if that is not the issues than when oyou said mixing valve is this on one of those parts thats like the blend doors or something that the dash would have to come out for very exspensive repair if that might be the issues ?

yesterday i took it in for refresh atleast thats what the dealership called it it was not lexus it was another dealer that had a promo free refresh up to 2lbs of freon and they also add the dye to it so that if it is leaking they can find it
so now its even worst now it warms down on both side driver and passenger side when im stopped and the outside time is like 75 or higher
did they just not add enough freon or is something else going on ? the second i start driving it starts to cool down the hotter it is outside sometimes the longer it takes to get to ice cold but eventualy it does get there

I (strongly) suspect they over-filled the system. Overfilled system worse than one that's has a too low charge.
BTW.. the number of recent cars that can use 2lbs of R134a is between Zero and None.
Got to a shop that *specializes* in A/C repairs, and have them check the system out; no need to go to Lexis, unless you need some REALLY expensive "free" lattes.
Good Luck !

You may have a leaking evaporator core. It is a very common problem on 07-09 ES350s. Replacing it is quite the project and I would be more comfortable with the Lexus dealer replacing it than just some random shop if it were my car. I probably wouldn't take it back to the place that did the a/c refresh.
