Started off intermittently, then only would work when truck was on.. now they wont open at all, unless manually... which isn't too bad BUT the tailgate doesn't have a key-lock or manual way to open.
Anyone have any tips or advice or can lead me in the right direction?

Thanks Much

If I remember correctly there is a relay for the rear doors which the tailgate lock is on also

Instrument Panel Fuse block - Test or swap fuses UNLCK1, LCK1, UNLCK2, LCK2. Those are the only 4 references I see to the door, but read every description and see if anything else matches.
