Rear Glass Antenna Mast

REAR GLASS INTEGRAL ANTENNA

The antenna grid pattern is located above the EBL grid.

For circuit descriptions and diagrams, refer to the appropriate wiring information. To detect breaks in the integral antenna elements, the following procedure is required:

1. Disconnect the antenna module connector from the antenna pigtail on the glass. Radio Antenna Module - Removal.
2. Using an ohmmeter, connect one lead to the disconnected module connector and with the other lead check each end of the grid pattern, on the opposite side of the glass, for continuity.

NOTE: The resistance should be below 2.4 Ohms on each line.

3. Measure the resistance of each line. The resistance should be exactly the same for each line.
4. If the resistance is not exactly the same for each line, check for a crack(s) in the grid. They may be hard to find as all the lines are tied together.
5. Even if the resistance is the same for all lines, do a very close visual inspection of the grid.
6. A break in the antenna grid can be repaired using a Mopar Rear Window Defogger Repair Kit or equivalent.
