Two problems related to wiper have been reported for the 1998 Chevrolet K1500. The most recently reported issues are listed below.
Wipers only work sometimes, very dangerous when it is raining.
We own a 1998 chevy silverado 4x4 that has wiper problems. The recall was issued for 1994 thru 1997 model chevy vehicles. Our son had a '93 that also had the same problems. The new "board" that was installed by dealers also would end up having the same problems. The solder spots were not large enough to cover the contact areas for the wiring and need repair in that form. We are still fighting the problem in our '98 and feel that due to safety issues during rain or snow that this should be recalled until fixed properly.
