Condition
Customer states:
 Static is audible on FM or AM channels while the rear window heater is activated.
 All channels are affected.
 The static disappears as soon as the rear window heater is deactivated.
Technical Background
Micro-cracks in the heating or antenna wires that are printed on the rear window can cause electro-magnetic
interference in the radio antenna boosters.
Most often, damaged heating or antenna wires are caused by outside influence, for example the storage of
objects with sharp edges (umbrellas or large containers) on the hat shelf or trunk of the vehicle that contact and
scrape against the rear window.
The application of window tint can also cause the wires to become damaged.
Production Solution
Not applicable.
Service
1. Verify that the concern only occurs while the rear window heater is activated. Otherwise, this TSB does not
