Power window/heater has no power to main fuse block - 85 K20 suburban.

[Brother Bill]

My power window receptacles, the silver 30 amp, and both heater fuses are not getting power fed to them.

Looking through the diagrams, they all get fed power from the ORN 300a and ORN 300b. I believe I found the plug above the steering column under the dash. Red 2C has power full time (non ignition power) and ORN 300 commons with brn/white 130.

From there I lose the trail, I'm struggling tracking it back any further.

Anyone have any insights?? I'm pulling my hair out!

The red wire, 3 RED 2, traces back to the fusible link attached at the junction block on the firewall, hence being hot or “BAT” power. It is spliced enroute to the ignition and feeds several fuses. Still working on the oranges...

I’m thinking 3 RED 2 feeds the power to the ignition switch and the switch feeds both orange wires. Really think you should just cancel your trip, take the column apart, again, and find the issue. Think how rewarding that could be.
