No AM, how to fix?

May have fuse blown, check fuses. Antenna may be disconnected.
Radio wiring may have come loose on back of stereo. Check all.

Antennae wire and other wires for the stock stereo are listed below:

If I remember correctly, FM and AM tuners are separate devices with separate antennas. Both devices are located in the trunk. Check antenna connections and fuses, then try with diagnostic tool and look for error codes.

have the radio checked out as the band change switch is not working. Try going into the mode /menu section of the radio and adjusting it there . Changing antenna does nothing as the radio works on either band with the same antenna

check your fuses first. You may have blown one.

1. If the fault is not visually evident, proceed to diagnose the integrated control panel (ICP) by entering the ICP Self-Diagnostic Mode.

ICP Self-Diagnostic Mode
NOTE: To enter the ICP Self-Diagnostic Mode, the ICP must be ON and in radio tuner mode (AM/FM).

1. Enter the diagnostic mode by pressing and holding preset buttons 3 and 6 simultaneously. This will suspend all radio functions, and display SP.

1. Preset Button 1 = Audio internal/external SELF TEST. The display will flash SELF while gathering the diagnostic trouble codes (DTCs), then stop flashing when complete. Press the TUNE UP button to display the DTCs if any exist. Record codes and refer to the following table:

ICP SELF-TEST CODES Code Description 0 No diagnostic trouble codes logged 1 No response from rear chassis unit (RCU) 2 No response from cassette player 3 - 4 No response from compact disc player 5 - 6 - 7 No response from remote climate control 8 - 9 Read Only Memory Verification failed

1. Preset Button 2 = Displays the feature strap for code identification, refer to the following table.

Code Description 01 Base-Electronic Search Radio (ESR) with Manual Climate Control (MCC) 07 Electronic Search Radio with Cassette (ESC) with MCC 17 ESC with Electronic Automatic Temperature Control (EATC) 97 Not programmed default of ESC with EATC

1. Preset Button 3 = ICP and RCU identification. This test identifies the software level of the ICP and RCU. The ICP is tested first, followed by the RCU. The display will have two sequences of three codes each. The first sequence is for the ICP, the second sequence is for the RCU. For code identification, refer to the following table:

Section 15-00: Audio Systems—Service 1999 Taurus, Sable Workshop Manual DIAGNOSIS AND TESTING Inspection and Verification NOTE: Many customers do not understand the limitations of FM reception. Refer the customer to the Owner Guide for information about the limitations of FM radio performance.

Internal diagnostic examination of the integrated control panel, rear chassis unit and audio compact disc player should be left to the authorized radio service center. However, the automotive technician should be able to analyze and isolate radio reception conditions to the proper area or component causing the condition. All radio conditions can be isolated to one of six general areas:

• antenna system
• integrated control unit
• radio speaker system
• radio noise suppression equipment
• rear chassis unit
• audio communications protocol network

Retrieving Diagnostic Trouble Codes (DTCs)
Using Audio System On-Board Diagnostics
The audio system has on-board diagnostic capabilities and is equipped to check for every component available in the system even if this specific vehicle is not equipped with all components. A Diagnostic Trouble Code (DTC) will be set for the missing components. These DTCs can be ignored if the vehicle is not equipped with these components. The battery must be fully charged for proper audio system operation. The ignition switch must be in the RUN or ACC position. Turn the system on, tune in a strong AM station and verify good reception. After an AM station is checked, tune in a strong FM station. The system is now ready to enter the diagnostic mode. Diagnostic Mode:
NOTE: Battery must be fully charged for proper audio system operation and self-test.

Enter Diagnostics mode by pressing SEEK DOWN button first and then pre-set button 3. Hold both buttons for five seconds. This will suspend all normal radio functions, retain the previously selected frequency and display DIAG.

1. NOTE: To perform diagnostics, press the appropriate buttons as instructed.
   
   SYSTEM CONFIGURATION SELF-TEST:
   Press pre-set button 1. This will check for connection of all possible devices and log the diagnostic trouble codes for any device that does not respond. The display will flash SELF while gathering the diagnostic trouble codes, then stop flashing when complete. To exit System Configuration Self-test, press pre-set button 1 again. To retrieve diagnostic trouble codes, press the TUNE UP button. This will display the diagnostic trouble codes if any exist. Continued pressing of the TUNE UP button will display the next diagnostic trouble code. Record codes and refer to the following table. To exit the Retrieval Mode, press pre-set button 1.
   
   
   CONFIGURATION SELF-TEST CODES Code Description 0 No diagnostic trouble codes logged 1 No response from rear chassis unit 2 No response from tape deck 3 No response from bezel microprocessor 4 No response from compact disc player 5 No response from steering wheel controls 6 No response from rear seat control 7 No response from remote climate control 8 No response from navigation module 9 Read Only Memory verification failed
   Remember, system configuration will test for all possible equipment connections. Inspect the vehicle to determine actual equipment installed.
   

1. Integrated control panel display test:
   To enter the integrated control panel display test, press pre-set button 5. This check will light all segments in the integrated control panel. The system will automatically exit this test after five seconds.
   

1. Integrated control panel and rear chassis unit identification:
   To enter this test, press pre-set button 3. This test identifies the software level of the integrated control panel and rear chassis unit. The integrated control panel is tested first, followed by the rear chassis unit. The completed test will exit automatically. For code identification, refer to the following table. The display will have two sequences of five codes each. The first sequence is for the integrated control panel, the second sequence is for the rear chassis unit.

Please rate this a fixya

Hello,
If the internal antenna is broken that means the ferrite bar is broken,that does imply that the wiring around it is cut. If the two parts are not removed, the antenna may still be able to perform correctly (just as two magnets put end to end). You can try to put it in the vicinity of another radio to see if there is any resonance effect.
Hope it helps.
