DETROIT – General Motors Corp. said Thursday it is recalling 1.77 million older pickups, sport utility vehicles and vans in the United States to replace windshield wiper circuit boards and motor covers.

The vehicles involved are 1994-97 Chevrolet C/K and GMC Sierra pickups and Chevrolet Tahoe and Suburban-GMC Yukon and Suburban SUVs; 1995-97 Chevrolet Astro and GMC Safari vans and Chevrolet-GMC full-size crew cabs; and 1996-97 Chevrolet Blazer and GMC Jimmy SUVs and Chevrolet S10, GMC Sierra and Isuzu Hombre small pickups.

GM said there have been no fatalities because of the faulty front wipers.

The recall is an extension of a windshield wiper replacement program GM conducted in 1998 and earlier this year on other trucks and vans.

Owners of the affected vehicles will be notified beginning this summer. Dealers will replace the circuit boards and motor covers at no cost to customers.
