GM rant>crappy wiring harness

So last week my wife drove the Suquinox and advised that the PS mirror doesn't work. No biggie as I don't adjust it anyway.

Yesterday the PS window did not operate. Wonderful.

I removed the door panel and did the standard power tests to figure out what is wrong. No power to the mirror or window. Only 1 side was out but I checked the fuses anyway and all was fine. By now, the speakers quit working as well. double wonderful.

A quick Internet search gave me many results that indicate broken wires in the harness where they pass from the door to the vehicle body.

I pulled back the rubber booty to find 6! broken wires.... On the side of the vehicle that gets used the least!!
I would expect this maybe on a classic car or barn find but not a 9 year old car.

This morning I pulled the door harness and spliced new wires in for the broken, shrink tubed them, and used harness covering. Everything is fine again and it didn't cost me anything but time.

That being said, the harness is pretty much foolproof to reinstall as the clips can only go to 1 component so I will give them a tiny bit of credit for that.
