It is pretty involved requiring discharging/disconnecting the AC, Dash board and other components. If you are up to it I found these step by step on the Autozone web site.

Looks like the low pressure switch gets power from a 10amp ac fuse. Power then goes to the ac relay which is powered on by the ac heat controller on the dash. Power then goes thru the high pressure switch to the compressor. The ac relay is grounded to the body. Do you have power on the lite and dark green wires going into the relay and is it grounded ?

see this steps and fix it. God bless you

Start the car and turn the air conditioning on. Allow the engine to run a few minutes so the air can cool. Check to make sure you have the proper buttons selected. This simple step may uncover the root of the problem.

2 Adjust the air controls on the dashboard to see how they are working. If the controls move the way they should with the proper amount of resistance and stopping in the right places but have effect on the air, then the problem may as simple as a blown fuse. If the controls are not working at all, then the problem is in the control panel.

3 Get to the fuse box in a Ford Explorer by removing the instrument panel to the left and slightly below the steering wheel. There is a fuse remover provided in the fuse box. A blown fuse will have a broken wire in it. In a Ford Explorer, this fuse is red number 10.

4 Find the control panel by prying off the top instrument panel around the air conditioning temperature controls. Unscrew four screws, one in each corner, and remove the temperature control panel. Unplug four electrical connectors and one vacuum hose to the control panel.

5 Listen for the blower motor to be properly working while the engine is running and the air conditioning controls are turned to high. Adjust them from low to high to make sure the blower motor noise increases and decrease accordingly.

pull heater control panel and check see if lights in this unit can be replaced otherwise the panel will possibly have to be replaced. The power for this comes from the instrument cluster and is not an individual circuit.

the ac/ heater controls is inside ur instrument panel/ u need to remove the instrument panel to give u access to check whats wrong with ur controls and u need set of tools to do that and be careful when removing panel boards as it easily breaks....

THE HAYNES REPAIR MANUAL.IT HAS ALL THE DIADRAMS FOR THE ELECTRICAL SYSTEM.IT HAS POWER WINDOWS - DOOR LOCKS - STARTING AND CHARGING -AC + HEATING - INSTRUMENT PANEL - INTERIOR + EXTERIOR LIGHTS - HEADLIGHT - CRUISE CONTROL - WINDSHIELD WIPER / WASHER SYSTEM.DIAGRAMS.ALSO HAS PCM AND ENGINE CONTROL SYSTEM DIAGRAM. SEE ITS WORTH IT.

On the drivers side ac/heating vent (to the left of the steering wheel on the dash) is a lighting wheel, this controls how bright your instrument panel is, move it all the way up
