I have a '99 RX300, 201K miles. The other day, when the AC reached the set temperature level, the fan speed reduced, as it is supposed to do. I wanted a little more air, so I reached over and turned up the fan speed control. Not the temperature control on the left, but the speed control on the right side. Well, it went to full speed and stayed there. No matter what I do, it will not reduce speed from full blast fan. This has been going on for a couple of weeks now. I have disconnected the battery overnight to drain the electric system, reconnected it the next morning, and still the same thing... full speed fan. Any ideas?????
