Sweating Bullets In Texas With Bad A/c On '95 Es300

[M_WM]

Greetings Lexi,

Have a '95 Lexus ES300. The A/C starts out well good and cold, air blowing. After about thirty minutes, the temperature goes warm and stays warm. Shut the car off a few of hours, A/C blow good and cold then about thirty minutes later goes warm again. Any suggestions keeping it cold. I think the compressor, freon, etc is okay. Otherwise it would never get cold. Is there a switch or something? Thank you, it's going to be a hot one this year!

The expansion valve is probably sticking. This is a very common problem with the mid-90's ES models.

The new valve is not very expensive, but the location of the part makes this a complicated replacement. Take it to an independent shop that specializes in auto AC.
