First started by stopping intermittingly, then you would depress the A/C button on the dash and it would come back on. Does this sould like the dash control unit or the compressor?
Thanks for your help.

Re: a/c compressor not engaging.
The contacts in the ignition key switch have been known to not make contact when the ignition is turned on. Remove the switch contacts. It can be removed from the key lock. Spray some contact cleaner into the contact cluster through some small openings, reassemble the switch and work the key back and forth to clean the contacts. Then see if the AC clutch gets voltage. Note that there is a little light in the AC pushbutton on the AC controls. The light some come on if the circuit to the clutch is complete

If you replaced the compressor unit, normally R-12 or what ever is used, is evacuated and thus they create a vacuum, then recharge the system to the proper level of gas/ pressure. Vehicles have a vacuum controlled shut-off valve to stop or reduce the flow of anti freeze from the engine to the heater core, near the condenser. There is sometimes a pressure control valve or switch to control, when the actual compressor unit clutch engages to start to pump the gas to cool the cabin area of the vehicle.
There are also fuses/ circuit breakers near the left front fender well under the hood, and left driver's side under left side of dash. I am presuming that the clutch assembly on the compressor functions properly engaging/ disengaging, when system is properly "charged."
If you turn the control on the dash to off and the compressor is still running, the relay is stuck or the clutch has failed to release. You should be able to unplug the compressor clutch and stop it too.
Hi. Take a deep breath of relief. First off this is not an error message and you should not panic. On your center console just below the gear shifter and the 4WD lever is an button that has "A/T MODE" written on it. This is what engages the 3 different driving modes to best assist you depending on the road conditions you are on. If the button is depressed at the top then the "PWR" mode is being used and on your dashboard you will notice a button flashing "PWR". This means that you have selected a driving mode that will avail you more power from the engine in instances like when you are driving up steep hills or a mountain or when you require to overtake a speeding car. Be warned, fuel consumption is high in this mode. When the button is depressed at the bottom, the "HOLD' mode is in effect and on your dash board the "HOLD' light will flash. This mode is best used when starting on a slippery surface like snow. Your car will start smoothly in second gear. When the neither the button is depressed at the top or bottom, then you are in 'NORMAL" mode which is for normal driving and where the car will run smoothly and use the lest amount of fuel. Hope this helps.
my 1993 range rover will not start when i turn the ignition, no dash lights, can not put it in gear, no power to the windows or seats. It has not shown any signs but it started and cut off and now nothing. The horn blows, head kights come on, the alarm engages when i lock with remote. Do fuses or the ignition control this? What could it be????????
