Rear defroster not working | Jeep Garage - Jeep Forum Nov 02, 2014So im new on this jeep, bought it few days ago. Sometimes when i go over 60 mph on a freeway i hear some like grinding/humming noise sounds like is coming from engine. Driver sideview mirror operates by hand but electricaly what might the issue be? Also rear Rear window defrost doesn't work. Relay works because I can Sep 28, 2009Rear window defrost doesn't work. Relay works because I can hear it clicking on and off. On switch lights up. Tabs are solid and don't see any breaks in the lines. Does this jeep (2001 jeep cherokee) have a seperate timer? Can the on/off switch be bad and still light up?
