Earlier this week I attacked the defrost fan. I had cut the hole in the glareshield and ran the wires to the switch a long time ago. But I hadn't finished the job as I needed to figure out where to route the wires to get them to the glareshield area.

I pulled the instrument panel out, then bolted the defrost fan in place. I lost a lot of time trying to puzzle out exactly what I had done when I ran the wires to the switch. I was in a rush when I ran those wires, so I hadn't bothered to draw up a wiring diagram for the system. I figured that I would remember exactly what I had done, and I would make the wiring diagram later.

I thought I had ran the wires from the fuse to the switch, and back to the instrument panel area. I hooked up the multi-meter, but I couldn't get any voltage on the wires. I eventually puzzled out that I had just ran the two wires to the switch, and not to the power or ground. This time I drew up a wiring diagram, then finished the wiring and test it.

I discovered that the defrost fan interferes with my original routing of the static line behind the panel. I need to order some different fittings so I can reroute the static line.

Today it wasn't snowing or raining, so I went out in the driveway and sanded some fibreglas. I went at it until I couldn't feel my fingers or toes, then came in to watch some football.
