air when its hots outside? I have a 1995 ES 300 Lexus, I had the A/C serviced recently but the air is still not working properly, had the freon put in and the dye, and in the mornings the airs blows out cool air, and in the evenings it blows out cool air, but when it gets hot outside the cool air stops blowing and then it starts blowing hot air. Please can you tell my what the problem may be?

you need to have someone look at the a/c again. it sounds like it is either low or maybe the condensor is going out.

You will need to get an expansion valve, the receiver dryer and the low side compressor hose. Back in `95, the low side hose would collapse and actually start to come apart from the inside and get stuck in the expansion valve. The dryer should always be replaced when any type of A/C work is done.
I`m going to assume you have no leaks and the compressor is still good and the dye they put in did not reveal anything. This should help you, but in can be expensive. Make sure you find somebody competant. I do work on Lexus for a living. This was a common problem on your ES300. You are probably looking at 5.0 hours labor plus whatever the parts cost. Good Luck!

it was serviced but not fixed...could be 1 of many.... condenser,,compressor...controller prob...
