Inspection |
Glass Antenna
Glass Antenna Circuit Inspection |
1. |
Remove the right rear pilar trim glass antenna, and then disconnect the power wiring from the amplifier. |
2. |
Turn the radio ON. Measure the voltage between terminal 2 of the harness antenna feeder cable (A) and body ground (B).
|
Antenna Grid Line Inspection |
1. |
Wrap aluminum foil (A) around the tip of the tester probe (B) as shown.
|
2. |
Touch one tester probe to the glass antenna terminal (A) and move the other tester probe along the antenna wires to check that continuity exists.
|
Glass Antenna Grid Line Repair |
To make an effective repair, the broken section must be no longer than one inch. |
1. |
Lightly rub the area around the broken section (A) with fine steel wool, and then clean it with alcohol.
|
2. |
Carefully mask above and below the broken portion of the glass antenna wire (B) with cellophane tape (C). |
3. |
Using a small brush, apply a heavy coat of silver conductive paint (A) extending about 1/8″on both sides of the break. Allow 30 minutes to dry.
|
4. |
Check for continuity in the repaired wire. |
5. |
Apply a second coat of paint in the same way. Let it dry three hours before removing the tape. |
Antenna Cable |
1. |
Check for continuity between the center poles of antenna cable.
|
2. |
Check for continuity between the outer poles of antenna cable. There should be continuity.
|
3. |
If there is no continuity, replace the antenna cable. |
4. |
Check for continuity between the center pole (A) of antenna cable and terminal of glass antenna (B). There should be continuity.
|
5. |
If there is no continuity, replace the antenna amplifier. |
6. |
Check for continuity between the center pole (A) and outer pole (B) of antenna cable. There should be no continuity.
|
7. |
If there is continuity, replace the antenna cable. |
Removal |
Glass Antenna Amplifier
1. |
Remove right rear pilar trim. (Refer to Body - "Rear Pilar Trim") |
2. |
Loosen the bolt and then remove glass antenna amplifier (A) after disconnecting the connector.
|
Roof Antenna
1. |
Disconnect the negative (-) battery terminal. |
2. |
Remove the roof trim assembly. (Refer to Body - "Roof Trim Assembly") |
3. |
Disconnect the connector (A, B) from antenna.
|
4. |
Remove the roof antenna (B) after loosening the nut (A).
|
Wireless Antenna
1. |
Remove the instrument cluster. (Refer to Indicators And Gauges - "Instrument Cluster") |
2. |
Remove the wireless antenna (B) by loosening the screw after disconnecting the connector (A).
|
Installation |
1. |
Install in the reverse order of removal. |
