Alright, i'v been going around and around with this problem. 99 two door two wheel drive blazer blue if you want to know. the door locks don't work, i pull the fuse and they cycle so they do work, i can hear them click when i hit the button, i can't find the relay anywhere all fuses are good and i have a battery drain. i need major help it's been off the road for a week while i try and find this problem.

 

Sounds like you may need to check the wiring for the locks behind the door.
