REAR WIPER WON'T WORK

2006 Buick Terraza

Electrical problem
2006 Buick Terraza 6 cyl Two Wheel Drive Automatic 60000 miles

My rear wiper quit, and the front wipers still work fine. Is there a relay to the rear wiper motor? The 15 amp fuse in the instrument panel is new and rear wiper still doesn't work. Or could it be the motor?

I would say your rear wiper is definitely fried. I would replace it. You can always tell by a corrosion buildup around the wiper motor shaft. Also testing the power and ground at the motor is a good way to check. But the motor is a very common failure in these vehicles.
