Suggest cleaning the relay terminal in the fuse box. I usually spray contact terminal cleaner and insert and remove the relay 20 times or so. Could try and contact Chevy and see if 07 was part of the recall. Affected all years, but recall only covered certain years. There is also an updated relay finally available, but cost is $80-$100+
