SYMPTOM/CONDITION:
Radio reception (AM or FM) is fine until the rear window defroster is turned on.
DIAGNOSIS:
1.
Start the vehicle and turn on the radio.
2.
Select an FM station between 98 - 101.
3.
Note the sound quality, then turn the rear window defroster on, and note the sound quality again.
4.
If the sound quality degrades greatly with the defroster on, check for a broken or scratched rear window defroster grid line.
NOTE:
Make sure there is no aftermarket tint or treatment on the glass.
5.
Pass the Remote Keyless Entry (RKE) Tester (Miller Tool No. 9001) over the individual grid lines of the backlight to determine the line or lines
