I don't understand your question. Are you asking how to replace the entire HVAC control unit or to replace its LCD screen?

The HVAC control unit in all LS400's is attached to the same metal frame that the radio is attached to. After you pull out the entire HVAC/radio headunit, it is easy to separate the HVAC control unit from the radio head unit.

Default Great climate control and ecu repair service!! I used them!

GO TO THE FOLLOWING WEB SITE: http://autoecu.com/ ON THE BLUE HEADER LINE THERE WILL BE A LINK CALLED "Active Listings", go to it and you will find an ebay listing to purchase their Climate Control Repair service. They charge $ 99.00 to replace the LCD and all burned out bulbs! and included will ship back you. I have used them and they were great. ALSO THEY NOW WILL REPAIR LEXUS ECUs for the same price!
I have on my desk right now an ECU and a Climate Control Unit out of a 94 that I am sending to them.

Best of luck ( For 99 it is well worth not messing with the unit!)

Default Changing bulbs on climate control

Changing bulbs no problem, changing LCD much trickier.
There is detailed description for changing bulbs somewhere here I just don't myself where it is.
here is a good post http://us.lexusownersclub.com/forums...dpost&p=342376
