I tried testing it in the relay - 30/87 always has power even when off? anyway, it sounds like it engages the clutch as soon as connected (obviously) but it doesn't solve the problem.
The drive belt is connected.... the freon is full, the blower inside the car works. the relay is good. but i don't hear the compressor cycling on and off?
The coil is an electro magnet that pulls the contact when energized.
A diode blocks the flow of current in one direction. In the AC case it is there to prevent current back flash when a high energy electro magnet (pump clutch) diengages.
A fuse is a strip of metal that is designed to break when exposed to a certain amperage.
Here is the wiring diagram for what you asked about.
Not everyone is good at electronics. I've always had an irrational block when it comes to this topic.
this is somewhat helpful, I'll look for an animated version to show how it operates in action

This second schematic is one I also found the other day and is what i used to attempt to figure out where the two wires coming off the compressor connector end up at. I first thought they would go to the ac clutch relay (87 and 30) and when that didn't work, i attached one wire to the clutch relay and the other to the diode. this also didn't work. Then someone else mentioned the relay #30 on the inside fuse box - tried hooking wires up to that and also didnt work. I feel like I am either missing something simple.
I recommend that you stop messing with potentially dangerous things that you don't understand or learn on something that won't fight back.
If you don't understand how a hinge on an arm works you are way out of your element.
