Hello, I have a 2000 GS300. When I was driving home from a workout today I noticed the dash was making a loud and disturbing nosie, it seemed to be the car's computer (or whatever the proper term is). It was a loud grunting sound, similar to that of a dog who is getting ready to bark IE "grrrr.... grrrr WOOF WOOF", minus the woof part of course. It isn't the usual minimal ratting noise from the dash that is common among Lexus's, this one was disturbing.
Any suggestions/ideas would be very helpful.
