Thanks CCKen. Those are very clear directions.
The only problem is that I won't be able to see the clutch engage from inside the car. Not sure if I will hear it.
Before I try this, I will try to push in the clutch with my hand just to see the difference of engaged vs. disengaged.
Then, after I turn the key, I will get out and go look at what state it appears to be in.

What's the temp there?
If it's under 60-65 then give up.
Lower than 30*F actually.
The A/C isn't designed to work during the winter. Pressures are way TOO low for operation. Refer to a temp/pressure chart. The high cycling of the compressor is due to low pressure such as being too cold.

It was not clear to me if it's safe to jump the switch while the car is on.
Thanks for the clarification. I will do this now.

The ideal method is to use a toggle switched jumper that you can control the on/off of the circuit. I made one (50 Amp) for jumping relay pin cavities in the PDC and JB.

My terminals are the opposite of this photo.
My low pressure switch connector has male prongs.
I will try to touch my paper clip onto the male prongs in there.
Or, I will try unhooking the other side of the cable connected to the low pressure switch, and try to jump the females on the other end.

I jumped the female connectors on the other end of the wire.
I also tried jumping the male prongs inside the connector.
(The photo shows female plugs. Mine has 2 male prongs)
The clutch did not engage.
What does this tell us?

I'm not following you.
You should have two PINS (male) inside the switch connector recepticle, and two PIN CAVITIES (Female) inside of the body harness connector.
My '99 has pins inside of the switch. The '98 XJ uses the exact same switch so you should have the same configuration.
You're not going to make a chruch out of a **** house on this issue are you.

I'm still confused about your pin setup, but if you jumped the two pin cavities in the wire harness connector (not the switch itself) and you didn't hear the clutch engage, start the engine with the connector jumpered and look at the end of the compressor drive. If the center portion of the compressor drive [pulley] is not turning, the clutch is not engaged. If so, either the clutch is shot or the wiring between the clutch relay and the clutch is open.

Here is my setup. Opposite of yours.
I tried jumping the male prongs inside the connector.
I also jumped the female connectors on the other end of the wire.
