Where is the cig fuse loacated on your 2007 Chevy Trailblazer?
The cig lighter fuse location in a 2007 Chevy Trailblazer is in the underhood fuse block. It's *not* typically in the interior fuse panel. You'll need to consult your owner's manual for the exact location and the fuse number (it's often labeled as "Power Outlet" or something similar, rather than "Cig Lighter"). The manual will have a diagram of the fuse box.
