Lexus Repair: 98 Lexus GS400 - fan speed constant on high, lexus gs400, fan speed

Question
My fan speed doesn't change when I move the selector  from High to Low.  It constantly blows high, even though it shows movement on the dash from High to Low.  Any idea how I can fix this myself?

Answer
Hello, In answer to your question about fixing it yourself. Without knowing your knowledge of Lexus electrical systems and the reading of wiring diagrams, it would be hard for me to say if it would be something you could fix on your own. I would say that if you do not have knowledge of these that you may be better off just bringing it to Lexus.
