Question about 2001 Lexus Gs 430
2001 GS430 has no heat, sometimes it will work by changing settings but extremely intermittent. System has dual control temperature controls and there is no heat in either setting, dual control on/off. When heat is on works fine but if a zone is changed, heat goes off and air is cold. AC system works great. Any suggestions or ideas on malfunction?

each dual heating control controls an actuator for a door to open and close may havea bad actuator motor for the passenger door should take to a shop where they can get body codes out of the system after market parts places like autozone cannot pull these codes most repair places can

your blend door on your passenger side is most likely stuck in the cold position. Chances are you cable is broken. Good luck.

SOURCE: Heating and AC problem.
I had the same thing on the same model car. Sounded like I had a gerbil living (running around in a little wheel) in my dashboard. I think the replacement part is called an accuator (it is relatively inexpensive) but the whole dashboard has to be removed to put it in. It controls the opening and closing of the vents. Apparently even taking the dashboard off is not as difficult as dealers often indicate - but they bill for a lot of time - so the job is an expensive one unless you do it yourself. I ended up having a friend do it for me.
