Left turn signal , door locks, and rear hatch button wont work

[sprinkl6969]

I have a 2002 chevy blazer. Just the other day i started experiencing problems with my blazer. The left turn signal only works sometimes. And it seems to stop working once it gets dark outside. My right turn signal works fine along with the hazards. But like i said before my left turn signal only works when it wants to. My power llocks stopped working as well as the rear hatch button and now i cant get into the back of my blazer and i have to manually lock my doors. The fuses seem to be fine. Help im out of ideas. Thank you.

Two items to check are the connections in the UEC and fuse block, and the BCM.
