I have a friend that got a hold of a service bulletin. Resetting the computer solves this problem. I had it on my 02 GS300. I took it to the dealer and the work order that they wrote was to reset the ecu. That really fixed my problem.
My 2002 GS300 smells terrible when I first turn on the A/C. Dealer said it isn't covered under warranty. That it was going to cost $150 for them to clean "something" with no guarantees it would help. Any suggestions?
