Technical Background

The small speaker in the left or right rear door has the same wire connector as the Advance Key antenna, although the color of the connectors and wires are different. During vehicle production the wire connections were interchanged between the speaker and Advance Key antenna which causes both the speaker and the Advance Key features to become non functional.

Production Solution

Improved assembly process.

Service

Determine if the small speaker in either the left or right rear door is not functioning. If so, remove the door panel and check to see if the wire connections are correct. The speaker wires are blue / white and the Advance Key antenna wires are yellow / brown. If not, switch the wire connections between the speaker and Advance Key antenna.
