| Does anyone have a wiring diagram of just the a/c system on a 7040? Wires are mostly gone on mine |

Found this in the service manual. Fairly simple system. Power starts at the blower switch then to evaporator thermostat, then to compressor clutch. The ground for the compressor clutch may still have the sub cool switch in it, all mine are straight to ground, I get rid of that. Also the switch on the power side disappears, that's another thermal switch, plastic body by compressor. I have seen a lot of wiring problems in those connectors by the firewall/dash area, lot of dirt in that area over 30-40 years. The connectors under the cab floor are the next area of concern. |
