I got my RX330's climate control set in auto with the a/c on. Sometimes the green light on the a/c button starts flashing--turning the a/c or the auto buttons off and on resets it and it lights up normally. Any idea?

 

I had that happen when I drove through a large rain puddle. After the belt dried all was well again.

 

A common problem on the RX 300, the flashing green light/compressor stall phenomonon appeared for the first time on my 330 about two weeks ago when splashing through a puddle. It's not so common on the 330, but it does happen. The fix is easy, as you say, just cycle the switch. It would seem there ought to be a better long-term solution.

 

yes, it has been rainy this week. Wonder if this is a defect that should be fixed?!
