Intermittent clicking noise from my inop antenna

My merc started yesterday to make a clicking sound from the automatic antenna which has never worked since I have owned it. It started before I even turned the key. I was putting luggage in the trunk and it started. Any ideas?

To stop the noise from returning, simply disconnect the electrical connector near the antenna motor (follow the wires out of the unit). this unit may be disassembled and thoroughly cleaned (especially the copper electrical contacts) to restore it to near new condition sometime in the future....about 3 to 4 hours for a novice.the clicking is due to the motor "coming alive" when an electric signal can get through the oxidized contacts. prolonged "clicking" may not harm the unit...there is some chance the antenna's nylon gear track has separated...try to pull up on the antenna itself after disconnecting car battery. if it cannot be pulled up, then chances are good for earlier described restoration. if motor housing looks VERY corroded, a full replacement of unit is best sol'n.

Remove radio, antenna and volume intermitent


Please describe your problem in more detail. Do you mean you removed the radio and now the automatic antenna and volume are intermittent? Or perhaps you removed both the radio and antenna and now the volume is intermittent. Or perhaps you want to know how to remove the radio and antenna because the volume is intermittent.

I think it's a problem with the radio itself. The antenna only responds when the radio is turned on / off. So the antenna sounds like it's working properly.

check the fuses and blower motor resister first. Some systems don't have resisters. Use blower motor speed control instead.


SECTION 412-04: Control Components 2001 Crown Victoria/Grand Marquis Workshop Manual
REMOVAL AND INSTALLATION Blower Motor Speed Control Removal and Installation
  1. Disconnect the wire harness connector.
  1. Remove the screws and remove the blower motor speed control.

  1. To install, reverse the removal procedure.





  • The blower motor is inoperative—EATC
  • Fuse.
  • Circuitry open or shorted.
  • A/C blower motor switch.
  • A/C blower motor resistor.
  • A/C blower motor.
  • Go To Pinpoint Test


----------------------------------------------------------------------------------------------
Electronic Automatic Temperature Control Module Self-Test
  • The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A diagnostic tool must be used to retrieve these concerns.
  • The EATC module self-test will detect concerns in the system control functions and will display hard diagnostic trouble codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 4° and 32°C (40° and 90°F) when carrying out the self-test. If the temperatures are not within the specified ranges, false in-car temperature sensor DTCs will be displayed.
  • The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated.
  • To enter the self-test, press the OFF and FLOOR buttons simultaneously and then press the AUTOMATIC button within two seconds. The display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed.
  • If any DTCs appear during the self-test, follow the diagnostics procedure given under ACTION for each DTC given.
  • If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Improper Operation.
  • To exit self-test and retain all intermittent DTCs, push the blue (cooler) button. The control will exit self-test, retain all intermittent diagnostic trouble codes and then turn OFF (display blank).
  • To exit the self-test and clear all DTCs, press the DEFROST button. The vacuum fluorescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared.
  • Always exit the self-test before powering the system down (system turned OFF).
  • Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.
