Two problems related to windshield wiper/washer linkages have been reported for the 2002 Chevrolet Silverado. The most recently reported issues are listed below.
Whenever windshield wipers on continuously for more than a few minutes the linkage "falls apart or pops off" leaving only the drivers side wiper working.
While driving the front windshield wipers failed without warning. The dealer diagnosed that snow build up under the wiper arms caused the linkage to "pop" off. Scc.
