2006 Lexus RX 330. Ac blows cold when moving. At idle, Ac light blinks and blows hot.
When car is moving, AC blows very cold. When car sits still for a few
minutes, recirculation light goes out, and AC light starts blinking. At that
point car begins to blow hot air. Took to local dealer who kept car two day's
and charged me over 500 dollars and said it had a bad relay. Drove the car
back to my wifes work. All seemed fine. When she left work, she pulled
over to make a call and the same thing happened again. I'm about to pull
my hair out! Anyone have any ideas what could be causing this? Many
thanks in advance for help!
