Looks like the high and low pressure switches provide the ground for the ac relay. Power for the ac clutch comes from the relay on the dark green and black wire. The relay gets power from a 10amp fuse.

Hello, i have a 98 ford escort lx, no power to a/c compressor, replaced high and low pressure switches,checked to compressor, replaced orfice tube, put freon, checked pressure (but its high), checked a/c...

There is a red wire going to the AC clutch, if you apply direct 12volts will it engage? If so, the constant control relay module (CCRM) could be defective. Hope this helps.

if you don't have any leaks it sounds like possibly one of the pressure switches are malfunctioning, or possibly a weak compressor relay

AC works when car is cold but will not start after car is hot. If I leave the car for an hour the AC works again...

Sounds like either the a/c relay , ON/Off switch or possible a high pressure switch.
All of these can be checked with a voltmeter.
Relay must have B+ going to it and leaving it .
On/off switch when removed from connector and bypassed with jumper wires should turn on system.
High pressure switch should have B+ on both sides of its terminals when system is on.
If your gonna do the diagnosis and repair yourself
you must do these tests when the vehicle is hot and a/c fails to turn on.
If you determine its the high pressure switch. I recommend you farm the job out (unless you have a recovery machine and a set of manifold gauges). It will be safer and cheaper to repair. Good luck.

Bad ground some where

There is a pressure switch on the side of the AC refridgerant reservoir area. If the switch is bad, or the level of refridgerant drops, the pressure switch doesn't allow the compressor to kick in. When you are running the wire from the relay to the compressor, you are bypassing the pressure switch. I am guessing that to fix your problem, you need to check the charge on the AC system, or check the pressure switch, and hopefully you will find your problem.!

1994 Ford Escort, will not start. i have replaced the starter, starter relay, and battery. the car still will not start. please help.

set the parking brake and make sure its in neutral then
try to bypass the ignition switch by jumping the starter relay under the hood. take the small wire off the relay and use a 2 foot piece of wire to go from the positive battery terminal to the terminal on the starter relay you just unplugged. if it turns over and if its a manual transmission the clutch pedal interlock switch may be busted, on the clutch pedal theres a small switch that senses the pedal is to the floor and it wont start. you can try to bypass that with a simple jumper wire. lastly if neither of those do it then you may have to drop the steering column and put a new ignition switch in it.

Just replaced the comprssor on my 2001 ford escort but it will not engage. tested the wires with a test light and I have no power plug that connects to the compressor. Key and ac are on.

Have you evacuated the system and charged it with Freon? There has to be some pressure in the system to activate the low pressure switch and allow power to compressor clutch.
