There are several fuses and relays on the 2011 GMC Acadia that control the tow package wiring/power. Under the hood in the fuse panel there is one labeled TRLR PWR for trailer power. Check that one first.

The others are labeled:
LT TRLR STOP/TRN (1 fuse and 1 relay)
RT TRLR STOP/TRN (1 fuse and 1 relay)
TRLR BCK/UP (1 fuse and 1 relay)
TRLR PRK LAMP (1 fuse)

It is also possible that a GMC dealer will have to do something to "activate" the tow package since your model did not come with the factory tow package.
