One Speaker Does Not Work (Balance and Fader Controls Adjusted to Mid-Posion

^ Substitute (but do not install) a known good speaker. If problem persists, check wiring between radio chassis and speaker for opens or shorts. (Shorted/grounded wiring may cause the speaker to appear dead, distorted or noisy.)
^ If wiring is OK, remove the radio chassis for service.

NOTE: Stereo radios have both speakers on one side of the vehicle (right or left) powered by the same circuitry in the radio. Therefore, if only one speaker is inoperative, the radio chassis is unlikely to be defective. However, the All-E MPX and Quad radios have four speakers individually. For vehicles with Premium Sound, also refer to Premium Sound Section.
