Any idea what’s wrong with my climate controls?

See if yo have power on the dark green wire to the compressor clutch with a call for cooling.

I saw no dark green wire, only a white and black wire.

What are the wire colors on the other side of that connector?

I can’t tell, they are sealed inside an outer casing.

edit: I tried unhooking the connector, the side with the sealed wires was putting out 0.05 volts with the meter set to 20 DCv on the connector that mated with the white wire, the other connector did not generate any voltage, the other side of the connector did not have voltage on either wire.

If you want to verify the wiring then peel some of the wrap back to see the wiring colors. Absent that, the black and white wires to the clutch are most likely ground and power so just probe them both and see if you get any power with a call for cooling. If nothing, probe each wire along with battery ground.

I did probe each one, see my previous post.

What do you get if you probe both wires in the connector?

On the sealed side I get 0.05 volts on the side that connects to the white wire, and nothing on the other connector that connects to the black wire, the other side, with the white and black wires, has nothing on either one. My meter was set to 20 DCv.

What do you get if you measure the two wires on the sealed side at the same time (one probe in each connector hole) with a call for cooling?

If nothing, then the positive lead in one hole in the sealed connector and the black probe to the battery negative. Then move the positive lead to the other hole in the sealed connector and leave the negative lead on the battery negative?

If none of these three measurements show 12V then you have a control issue. If you get 12V on any of these three measurements then the compressor clutch is toast.

All of the measurements were with the black lead to the black terminal on the battery.

I have not yet tried measuring both at once, I’ll try that tomorrow.
