For your vehicle there is a Bullitine on your complaint. This has to do with your rear window defroster grid. The rear defroster grid can have tiny cracks within the grid which will end up randomly distorting or making your radio static. If you would like further information on how to repair this complain please respond.
Some customers may comment that the radio has poor reception or radio static/increased interference when the rear window defogger is turned on. Also, some rear window defogger grids may be inoperative.
This condition may be due to microscopic cracks in the electrically heated grids of the rear window defogger. These cracks may cause electrical interference when the rear defogger is on and this could affect radio reception.
The addition of vertical grid lines to the heated back window defogger circuits has made it difficult to detect broken defogger grid lines. In the past, it was a simple matter to use a voltmeter to check the continuity of each grid line in order to locate a non-functional line. New design back windows have two vertical grid lines that connect all of the horizontal grid lines together, thereby providing alternate routes for the electrical current to follow. This makes the old test method ineffective.
There are three distinct zones across the back window that must be checked. They are:
To detect a broken grid line in any of the above three zones and to isolate the exact location of the break, perform the following:
Important: The first place to check should be the driver side segment 2 to 3 lines up from the bottom about 380-385 mm (15-15.2 in) from the buss bar.
