My power door locks and rear dutch oven door will not operate, what should I do? on 2000 GMC Safari

I have checked the fuses under the hood and behind the brake pedal, but do not find one labeled power locks. Everything else works fine.

Fuse function and location info. is in the owners manual. Or check each and every fuse you can find with a test light IF you want to be sure!!

Have you tried all the door lock switches, or are you using the key fob.
