One of the more fragile systems in your car is the rear-window defogger. Fortunately, it’s also one of the easiest to repair. If you notice that the rear window isn’t melting ice or drying condensation, check over and repair the defogger in your Saturn VUE.

Service a Rear-Window Defogger
Pop the hood and locate the fuse box, which is a covered box on the driver’s side of the car close to the windshield. Pop the top off, and find the fuse labeled “rear defog.” It should be 25 amps.
Check to make sure that the fuse isn’t blown or broken internally. Both sides should register on a voltmeter.
