Tracing the dash A/C

[PaulRVer]

We are trying to get the dash A/C clutch to engage. Here is what I have.
The pressure is the same as what is in a can.
The fuse at the dash is showing 12v on both sides with A/C on.
My son saw what looked like a white and dark wire going to a sensor on the heat exchanger by the dash. He jumped the two and nothing.
The wire at the fuse is brown.
The wire feeding the A/C clutch is blue.
What is between the two?
My guess is fuse, relay, pressure switch, clutch.
Is there a diagram?
Where is the relay?

That is one of the reasons I like a test light over a volt meter.
Often with a poor connnection the VM will show good voltage.

But the Light, which places a small load.. will be very very dim if it even lights.

Had a wire fail... NOT a connection but a wire 10ga Stranded a good foot or two from the nearest connection..> Dang thing had a big bump when I investigated.. one end of the wire BRIGHT LIGHT.. other end 11.5 volts no load and no light.. Excised the bad spot and soldered and heat shrank over the joint and BRIGHT LIGHT and the radio worked again (50 watt Ham VHF/UHF D-Star radio.. Kind of a power sucker)

I can test a dozen fuses in the time it takes a volt meter to test 2.

It is a 1997 Monaco Windsor. I spent a few hours looking on the web.

There is a diagram... Now depending on the make and model of your RV or vehicle the odds are likely in the 90% or better range that a standard CHLITON's or other manual applying to the chassis your vehicle is based on will apply.

I think Chiltons's makes a Air Conditioning manual.. Colors may vary from vehicle to vehicle but the basic diagram is the same and there are but two

One has a switch (that's in the dash) which MAY operate a relay.. Either the relay coil or the power to the compressor also runs through a sensor or two.

Other than the clutch winding (A magnet) Not much I left.
