Can you share a pic of the glove box RPO codes? When you turn the headlights on, the amber lights come on?

The lights on the driver side mirror come on. Nothing works on passenger side.

If you can provide some pics of the glove box RPO codes, that’ll help.

I will do it in a few hours. It’s throwing me off because the mirror worked when I plugged it into driver side. Hopefully a harness issue. But the door lock and window switch on passenger side work.

It’ll be hard to troubleshoot because you just bought this truck and no telling what the previous owner did. With High Country trucks, the door panels have to be plugged before testing since motor commands flow through the door panels.

I think with it being wrecked previously. They bought the cheapest they could find to replace parts wise. The mirror probably came off something other than a high country or is aftermarket. I just dont understand how it works fine when plugged in driver side. But nothing on passenger. Do you have access to what color code wires are supposed to be in the plug feeding the mirror? It’s obviously got power from door jam plug to the harness because window and door locks work on that side

You’ll have to do some digging in the door panel. With your build, some of the commands go through the window switch. If you look at the window switch, there are 2 connectors. One is for the window itself and the other connector is for the mirror commands. If I recall, the glass adjust and mirror fold, along with memory go through that window switch.

So you’re saying that nothing at all works? No lights, no fold, no glass adjust?

Correct nothing works. I looked at the harness in the door jam. The wiring pins don’t line up. Do you have access to a wiring diagram to show color codes to the pins?
