Hello, I have a 2002 crown vic and had to have the heater blower moter replaced. The moter was replaced and it works fine but, now the clock in the radio does not display. The radio disply is fine its just the clock. Does anyone know hoe to go about finding the problem? any suggestions? The shop who did the work refuses to accept responibilitiy. Thanks to any and all who answer.

Try running the ACM test for DISPLAY and see if it fails..

ACM Self-Diagnostic Mode (P100i Only)
NOTE: To enter the speaker walk-around test or ACM self-diagnostic mode, the ACM must be turned on and in radio tuner mode (AM/FM). The ACM self-diagnostic mode can only be entered while in the speaker walk-around test.
[ol][*]The ACM self-diagnostic mode (P100i only) has five tests available:[*]Preset button 1 = Audio internal/external SELF TEST. If SELF FAIL is displayed, press TUNE > to scroll view the diagnostic trouble codes (DTCs) stored. Refer to ACM Diagnostic Trouble Code (DTC) Index. If system is OK, SELF PASS is displayed.
[ul][/ul][*]Preset button 2 = View/clear continuous DTCs. NO DTCS is displayed if no DTCs are retrieved. If DTCS FOUND is displayed, press TUNE > button to view the DTCs retrieved. Refer to ACM Diagnostic Trouble Code (DTC) Index. To clear all DTCs, press the EJECT button. DTCS CLEAR will be displayed.
[ul][/ul][*]Preset button 3 = SIGNAL TEST. This test measures the average strength at the current tuner setting.
[ul][/ul][*]Preset button 4 = Software configuration level. This test queries each radio system controller for their software configuration level. SOFT LEVELS will be displayed upon completion of the query. Press TUNE > to scroll view the software configuration version level.
