Hey guys, owned my chevrolet blazer for almost a year now, just lately the door lock switch and mirrors have stopped working.
It's a 2001, 4 door, awd
Today I tested to see if I had power getting to the switch which I do not, I pulled the door card of to look at the electrical connector, once testing I realised that black and blue connector above have no live coming through any of the wires, however when I use my circuit tester, I can power the switch and get all locks and mirrors to work.

So far, I've tested all fuses, all ok, wiring all seems to be ok even in between where the wire comes out of the interior into the door through the rubber sleave.
Tested the relays all seem to work, however when testing the constant live of the relay holder, only one shows to have constant power, the other two that effect the locks don't have constant power, I'm thinking the issue must be after the engine compartment fuse box but before the interior relay box,
I was wondering if anyone has had anything like this before?
One minute everything was working absolutely fine, the next I had no power, its been like this a couple of weeks now.


Thank
Chris
