After I already bought a used climate control deck from an 03 (I have an 01) I read that the plugs in the back are different, which they are. If you take off the face of the climate control, and unplug the ribbon wiring and switch it to your original climate control deck it will work (if it worked prior). Our climate control deck was ugly with fade and this worked out for us. Lexus parts guy said that you can buy knobs and the face seperate from the entire deck so I am sure it is possible to seperate the deck from the facia. Don't be scared to buy an 02-05 if you have an 01 or vice versa.
