Windshield wipers failed to operate in driving rain resulting in extremely low visability. Vehicle was pulled off the road, ignition was shut off and started again in an attempt to get wipers to work. Wipers still failed to operate. Car could not be safely operated until rain had ceased. This is a known failure on many GM vehicles. We had a similar incident in an S-10 truck approximately 2 years ago, so we were familiar with problem.

Windsheild wipers works intermittentlyon a family trip had to get out and tap the windshield motor box on the firewell, and then they work. I learned of a recall, but it didn't extend to the year 1999 I think it should, and if you think it should please send me a recall. Thank you.

Windshield wiper malfunction is a problem in my 1999 Yukon. GMC does not want to address this seriouse problem.
