My first brick was a 1975 245DL. The ac switch was a rocker switch on the control panel. Now it's full circle, with the newer 240s again having the rocker switch.

You and I have, however, the turn-the-knob type. The most critical part is the silver tube that runs from the switch to the refrigerant line near the expansion valve. If that is broken the R-12 inside is gone and the switch won't work correctly.

Wiring - from the Volvo Service Manual Wiring Diagrams for 1987-88 240s.

i know which wires they are-i believe two green, one red and one yellow/blue. the colors may be wrong but i know which wires to use. i just don't know where on the switch they're connected.


Blue or blue-yellow to the bottom side terminal on the microswitch.

Red to the other terminal on the microswitch. That terminal has a 90deg bend in it.

Green - diagram is ambiguous here.

One green goes to the terminal on the bottom front of the switch, and the other green (2 wires, shown) goes on the terminal on the upper back of the switch.

I hope you can get some sense out of this.

Good Luck,

Bob
