AIR CONDITIONING

2003 Lincoln Town Car • V8 2WD Automatic • 119,000 miles


2003 Lincoln Town Car AC Compressor
Air Conditioning problem
2003 Lincoln Town Car V8 Two Wheel Drive Automatic 119,000 miles

The AC Compressor now takes about 10-20 minutes to begin cycling after the car is started with the AC on. When it does begin to cycle, the AC system works perfectly and cools well. Any ideas why it is taking so long for the compressor to start?

Air Compressor and dryer have been replaced. System has been recharged.

Sorry check em this way.
Dual Automatic Temperature Control Module - Display Continuous Codes
 This function will display continuous (intermittent) codes and hard faults that occur during
normal operation.
 The display of continuous codes can be initiated at any time. Normal operation of the system
stops when the display of continuous codes is activated. Note that "° C " will be displayed
while in this mode.
 To display continuous codes, press the OFF and PANEL buttons simultaneously and then
release and within two seconds press the AUTO button.
 To exit the display of continuous codes, press the FRONT DEFROST button. This will exit
and clear all DTCs. Press the FLOOR button to exit without clearing DTCs set before the last
ignition cycle.
 Always exit continuous codes display before powering the system down (system turned off).
 Continuous DTCs are saved only after an ignition cycle.
 Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent
condition occurs.

Look at your owners manual for identification of the fuses and relays. Identify the AC Clutch in the fuse box on the passengers side under the engine hood. Remove and replace the relay.

If you are inclined to do so, you can swap the Horn relay and the AC Clutch relay and that will also fix the problem. The horn will still work and the air will have no delay. The AC Clutch relay is 204, and the Horn relay is 201.
