Hi guys, currently own a 2001 awd 4 door blazer.
Having an issue with the door lock /unlock switch and mirror switch.
I've checked and have absolutely no power at all getting to this connector what's inside the door card on any of the wires. I've checked fuses all ok, tested the relays all ok.
When I put power to the switch all works as should, I'm guessing the issue is obviously before the interior relay box, has anyone else had these issues, anyone recommend what else to look for. My guess is that where the loom comes through the firewall, it may have a damaged wire, I just can't believe the entire electric connector doesn't have one wire getting power.

Connector I'm talking about is the black and blue one


Thanks
Chris
