Question about 2001 Lexus RX 300

1 Answer

Heating and AC problem.

The AC only gets cold if blower is on Max. Otherwise, it blows hot air. I can hear clicking under the passenger side dashboard. I suspect there is a malfunction with the doors that control the airflow to the heater core but I am not very familiar with this car. 2001 Lexus RX 300. Thanks!

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.

2003 Ford Explorer XLT Air Conditioning vents blow hot and cold


It sounds like the control motor switching from hot to cold is stuck halfway in between the two temp settings. You will have to take it down and replace it, it is mounted under dash passenger side near the blower motor.
