Signal Description, Climate Control Module (CCM), Connector C
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
There is no breakout box for this connector.
NOTE:
From and including w50 2001, the fan is connected directly to connector C with no wiring in-between.
