air conditioning problems
so today it got pretty hot, nearly 90 lol and i turned on the ac for the first time.
it never got cold, all it would blow is warm air. has anyone else had this problem....maybe the climate control is confusing and i'm missing something but i did everything i could including setting it to LO.
strange thing is the driver's vents were cooler than the passenger's vents which felt like heat even tho i tried LO LO and dual on/off, whatever. in any case, neither never came close to being cold. could this be a problem with the vents and their possible reinstallation issues?
wanted to check her first before i take it in, i'm sure it is minor but no way i can survive next month without air.

What temperature are you setting it to? You separately set your side and the passenger side. Use the up and down arrows to bring it up (hotter) or down (cooler). You've got NAV too, so you can tell "Lexie" warmer or cooler and temps will adjust that way also, plus the climate control screen. There are three options I know of for lowering and raising temperature.

All you need to do is to push the "auto" button. If the cabin temp is much higher than set point, the air should be directed up to the vents, the air source should change to recirculate, the fan should come on "high", and the compressor should be switched on.
If the air coming from the vents isn't cool in about 10-15 minutes of driving , it's probably time to bring the car to the dealer.
In most cars, the doors that bypass the heater core (air passes over the evaporator at all times) is behind the glovebox, not by the vents, but I'm not that familiar with the Lexus.

I do agree that the AC leaves a bit to be desired. Mine definatly gets cold, but it takes several minutes which is pretty bad since its such a small cabin and we've yet to hit 80 degrees here. However if yours isn't getting cold at all with the AC on and temp set to low, there is something wrong.

toggle the A/C button and it barely makes a different but I do hear the air conditioning motor going on and off. just ran for 30 minutes and back to my garage, not a drop of water or moisture, nothing dripping. Is that unusual?
I believe something is wrong, to fix this or take or look or whatever just know what you know, do you think they will have to remove the Nav unit?

No brilliant repair tips from me. You've done everything I can think of. Yes, the air conditioning system in my IS is weak. Probably one of the weakest I've ever owned but it sounds like yours is definitely broken. NUTS. Just take a deep breath and visit your dealer. GAG.
I had a new Lincoln Mark VIII and right out of the chute it was NG. I was SO ticked off there were no words. But it did get solved and your probelm will too.

These complaints about the A/C are interesting. Some of you may recall that last summer BOTH Road & Track and Autoweek magazine complained that the IS test mules had inadequate air conditioning.
Seeing as I also live in central Texas (hook 'em), when Car & Driver magazine sponsored that "ask the Lexus IS engineer a question" forum last fall I sent in a question about the A/C complaints from the automotive press. The Lexus engineer did not respond to my question. Then Edmunds sponsored that live chat with the head of US Lexus marketing last October. Again, I asked about the A/C issue. Once again no response.
While the IS350 is currently at the top of my list for a new car, I think I will wait to see how my fellow Texans with IS's fair this summer. Based on this thread it looks as if things are not looking good.
