My brother-in-law has an ES300-2003 Lexus and the air conditioner is not
functioning properly in that when you turn it on it will work ok for awhile and
then the indicator light on the control flashes, as a result the air conditioner shuts down. After several attempts to restart the a/c it will start and run for awhile and then shut down again. Any suggestions as to what may
be the problems.

I am having the same problem with my 2000 RX300 - does this same fix still apply even though the fuse/relay box is set up different?
