2012 C2 95th anniversary edition. None of the heated mirrors are getting power. The one fuse is good and the switch is good. Anyone seen this before? Getting ready to tear into it tomorrow, but hoping someone found a magic hidden plug that comes apart on its own somewhere.
No power or no heat? Power comes from chassis module up through floor connector behind access panel under switch cabinet. No heat possible because the mirrors have poor heaters with loose contact at spade connectors and burn the grid out at one connector or the other.
Do you have a Nexiq or some other data translator for your computer? If you do you can just hook the adapter to your computer and go to service link and when you get to the serial number screen type in the last six numbers, when it opens and shows modules on the left click on bulkhead and then go to configuration and click on that. If you click on print you can print the pinout list for this unit. I think you will find the heated mirrors in chassis module area. If you have hooked to the unit as a first step you can then go to the module for heated mirrors called out in the list and click on templates. Use the j1939 line and click on that and a list of connectors will populate the section pick the connector that has the pin you want in it and click on it. Be patient!! when it opens you will see a screen with boxes and letters corresponding to the pins in this connector, turn on the heated mirrors and see if the block turns yellow and how much amperage is used. If it is zero you have an open wire or driver. you can also back probe at the module at the pinout called for to see if power is actually coming out of the module. Have fun.
