2005 trailblazer , mirrors heat up when I hit the defrost button , but nothing to the back window. I pulled the trim and power going to the liftgate module is okay , the lines on the glass all show continuity when tested , now when I went to test the fuse there was no power , then I realized that the fuse might only be powered when the relay clicks on. stupid me pushed the tester in to hard and now the fuse is loose.
is the relay in the liftgate module itself ? I assume the climate control unit is working correctly since the mirrors heat up.
any ideas on what to test ?
