RADIO - FRONT SPEAKER - "BUZZES" WHEN THE RADIO/CASSETTE IS OPERATED AT MODERATE VOLUME AND SET WITH HIGH TREBLE OR LOW BASE


LINCOLN-MERCURY: 1991 CAPRI


ISSUE: The front speaker(s) may make a "Buzzing" sound when the radio/cassette is operated at moderate volume and set with high treble or low base. This occurs because the speaker wiring is damaged or moisture has entered the speaker mounting area.

ACTION: Check the speaker and cone wiring for damage. If necessary, replace the speaker. Also, be sure that the watershield is properly sealed. Refer to the following procedure for service details.


1. Remove the door trim panel from the door with the speaker buzz. Refer to the 1991 Capri Service Manual, Page 45-03-01, for the removal procedure.

2. Remove the three (3) speaker attaching screws and temporarily remove the speaker.

3. With the speaker in hand, operate the radio to confirm that the speaker buzz still exists.

^ If the buzz does exist with the speaker in hand, replace the speaker (E9JY-18808-A).

^ If the condition does not exist, then continue with Step 4.

4. Disconnect the speaker wiring and remove the speaker.

5. Remove the door handle reinforcement bracket, if necessary, and carefully peel back the watershield.
