Rear window defogger
Hi All,
2002 impala, My rear window defogger has stop working. I'm thinking I should try swapping the relay first. Does the impala have a defogger relay and if so where is it?
Thanks
John

RE: Rear window defogger
relay is in the door jamb on the passenger side
check for power at the window with the switch on. If no power, then pull the c pillar covers off and there will be an antenna module that the defogger circuit runs through. Check for voltage on the green wire with the switch on. Again if no power, next in line is the relay, then the fuse, then bcm or hvac controls
