2013 jetta cigarette lighter fuse location 2012 Volkswagen not working / Make cigarette lighter switched by

Check the metal strip inside: If the strip is broken or dark, the fuse is bad

This Sierra has 2 different fuse boxes where the cigarette lighter fuse is located: Instrument Panel Fuse Block (Left) Fuses and relays related to the cigarette lighter: Instrument Panel Fuse Block (Right) Fuses and relays related to the cigarette lighter: Why does the cigarette lighter (power socket) fuse blow in the Sierra

Test the fuse with your multimeter, then try out the lighter socket

I just went out and checked after reading your post and when I turn on the blower fan, to any setting, I get no fan power at all so I guess my car is wired differently from yours somehow
