SYMPTOM/CONDITION

Radio reception coming in weak on FM stations and not at all on AM stations may be due to the antenna plug short circuiting inside the radio. This condition is similar to a failed antenna.

DIAGNOSIS

To determine whether the radio or antenna is at fault:

1. To gain access to the back of the radio, slide the radio out of the instrument panel without disconnecting any wires.

2. Turn radio on and tune to a local AM station.

FIGURE 1:

3. Pull the antenna plug out of the ferrule about 1/8" (Figure 1).
If the radio starts playing, remove radio and send to a warranty repair station. Mark the repair order:

ANTENNA FERRULE PROBLEM

If the radio does not play when the antenna plug was pulled out 1/8", substitute a known good antenna to determine if the car antenna is defective.
