I did a search on the forum. But didnt see this same issue:

Vehicle: 1998 LS400 with 155K miles

Anyone ever measure the A/C outlet temp at the dash vents? It was brutally hot yesterday in VA. Temps in the mid 90's and 90% humidity. I have a fairly accurate temp probe throughout my other vehicles to measure the temp. I took the reading at the hottest part of the day around 5-6pm and it read 50 deg F.

Not sure if its a fair comparison but our other two vehicles (97 & 06 Honda Odyssey) both read 40 deg F. at that same time of day.

thanks

first, no I never have, but there are a lot of things to consider..

As the days become warmer, the A/C system has to overcome the temps. The newer cars tend to be able to blow cold immediately where older tech may take a bit. Ours doesn't get to good temp for about 4-8 minutes of running and that varies with ambient temps. Once it is cold, it is cold.

I have reply buried among one of the threads that had a similar question. I don't recall the exact temp off hand.

Agree with ra40. By the time the engine temp has reached half, the a/c is freezing which coincidentally in warm weather only takes 3-4 minutes.

Being in FL, we take a/c seriously. In fact, each state has two statues of prominent individuals located in the US Capitol building. One of FL's is the guy who invented a/c...

Humidity has a lot to do with the cooling effect.

Use your key fob to lower you windows and open the roof to let the hot air out. After 30 secs, close them. That will help cool your car more quickly.

Also, use a reflective windshield shade, and tinted windows.

I also follow the exact same procedure and it works well.
