To receive VHF, the remaining conductive paths serve, which simultaneously serve as heating elements. The insufficient height of this antenna system is compensated for by an amplifier under the left-hand rear roof pillar trim.
Troubleshooting the Rear Window Antenna
The roof pillar rear trim can be removed with great patience and dexterity in vehicles with reclining rear seatbacks without other dismantling work. But in cars with a hard back, you can’t do without dismantling it. In general, the work is facilitated by removing the rear storage pocket and the side trim of the reclining seat (chapter Salon).
1. Remove both facings of racks of a roof behind.
2. Check the ground connection of the rear window heating on the right roof pillar, and also whether the antenna amplifier is securely connected to ground with the fixing screws.
3. Carefully check the top three conductive tracks on the rear window: is there a visible break? If so, repair with conductive silver lacquer or install a new rear window.
4. Now comes the electrical test: Disconnect the thin white lead wire connector at the top of the amplifier, measure the voltage to ground. To do this, turn on the radio.
5. Presence of voltage from the battery: the current supply to the amplifier is in order. No voltage: Repair open in wire.
6. On the same wire, measure the current between the amplifier connector and the removed wire.
7. The ammeter should show 30-50 mA, otherwise the antenna amplifier does not consume current and, therefore, it is faulty - replace it.
8. Next check: disconnect the lower wire on the heated rear window, turn on the ignition and heated rear window, measure the voltage in the wire.
9. It must have battery voltage, otherwise the fault is in the lead wire or in the amplifier, outline the damage.
10. Disconnect the lower (thick white) wire on the amplifier, measure the voltage with the ignition on and heated rear window:
11. If there is battery voltage, then the lead wire is in order, the amplifier may be faulty. If not, then vice versa.
Speakers in front door trim
The mid-range speaker located at the bottom is also screwed to the rear of the door lining. Numbers from «1» before «3» fixing screws are marked.
1. Remove the front door trim.
2. Carefully remove the foam plastic damping film behind the door trim.
3. Disconnect the wire connector in the connecting wire from the lower to the upper speaker.
4. Midrange speaker: Loosen the three speaker fixing screws and remove the wire guide.
5. Treble speaker: Loosen the Phillips head screw on the back of the speaker, remove the speaker.
Rear speaker
The rear speaker is screwed from above to the metal of the body under the receiving pocket (arrows). To dismantle it, you must first remove the rear receiving pocket.
1. Remove the back pocket (chapter Salon).
2. Loosen the Phillips screws, remove the speaker.
