Looking to obtain a wiring diagram for the 2006 S65 AMG. Having some issues with front dash heater circuit not getting any electricity to the fan unit there. All the fuses checked out good best that I could pull and visually inspect. Guessing it might be a fuse on the F1/6 - Right Side Of Dash fuse compartment inside car. Fuse F90 is listed to run the current through to the Heater Unit ?? Any suggestions on the best way to troubleshoot the issue when all fuses are functional ? Could it be that that the Fan Motor has a bad spot in the windings etc ? Any suggestions help.

Thank You,

WA S65AMG
