I have been looking through google images, but I can't seem to come up with a wiring diagram for just the driver's power window switch. One that is color coded so you can be sure. For an 87 R10 single cab truck. It's the one that has two switches and is a rectangle not a square. I'm trying to diagnose why the window only rolls up, and I've tried a brand new switch but no luck.

There's lots of diagrams for the whole door including the electric motor and power locks. Below is the only one I could find, but it's for doing the relay mod. Hopefully they didn't move anything around. I'm not great at reading electrical diagrams. Looks right, but I thought I would run it by you guys first. Since collectively this board knows everything about these trucks.

Can I use the color coding in this diagram to diagnose?

Thank you

Looks like the correct diagram.
Mine was doing that and it ended up being the wire on the plug that connected to the switch. Looking at it, it looked fine. I barely moved it and SNAP.

Yeah I figure it's something like that. I just installed a new plug because the old one was done for.

With each wire labeled it should be easy enough to pinpoint the problem. Nice for any future problems too.
