DCCV... Anyone ever replace their's?

Anyone ever replaced their Dual Climate Control Valve (DCCV) on a 00-02 LS? If so, what was involved, where is this piece located? Is it better to have someone else do the work. Any help is appreciated.

Are you referring to the Dual Coolant Control Valve? According to the service manual, the parts list is:
Item - Part Number - Description
1 12A647 Ambient air temperature sensor
2 19C734 In-vehicle temperature control sensor
3 19E663 Dual sunload sensor
4 19E616 Panel door actuator
5 14N089 Blower motor ignition relay
6 19E624 Blower motor speed control
7 19805 Blower motor
7 18504 Blower wheel (not serviced with motor)
8 19E616 Air inlet door actuator
9 19E616 Cold air bypass door actuator
10 19C734 Passenger air discharge temperature sensor
11 19C734 Evaporator discharge air temperature sensor
12 19E616 Floor door actuator
13 14N089 Heated wiper park relay
14 19E616 Defrost door actuator
15 19C734 Driver air discharge temperature sensor
16 14N089 Electric water pump relay
17 18495 Dual coolant control valve
18 19980 Dual automatic temperature control module

If you send me private message with the part you are looking to replace and an e-mail address for you that can accept PDF attachments, I can e-mail to you the relevant section from the factory service manual.

Fortunately, I have not had to do anything with the climate control system.
