Air Conditioning problem
2001 Lexus GS 300 6 cyl Wheel Drive Type unknown Automatic 120000 miles

The heat on the right side (passenger) side does not heat. Even if the dual air system is activated, the right side does not heat at all. The air is blowing, but it is cold air only. Should I check the fuse first before taking it in to the dealership?

I am having the same problem as keto35, but the ac blows hot air on the left side, and I want cold air to blow on both sides. I have replaced a air flow control box on the right side. I just recharged the AC system, but I am still having the problem. Are there two controllers under the dash instead of one.
