2002 Buick Rendezvous 6 cyl All Wheel Drive Automatic 186000 miles
My reverse lights, license plate light, and rear wipers don't work. However, if I turn on wiper and then move wiper manually the license plate light comes on. If I put car in reverse and do same thing reverse lights come on. And nothing will shut off until I put car in park and then move wiper blades manually again. What can I do to fix this? Car is up for inspection at end of month.
