Under the cover on the end of the wiper arm on your 2001 Chevrolet Suburban your should find a locking nut which may be loose. Before tightening the nut it would be best to remove the arm and check the splines on the transmission. If you remove the nut and the wiper arm your may see metal shavings in the splines of the wiper arm transmission. clean the loose metal with a small wire brush. With the wipers in the rest position reinstall the arm positioning it to match the one which was not removed. Tighten the locking nut securely. If the wipers now working ok great, if not splines on the wiper arm or the transmission may be to worn and require replacement.

This might be easy. Get the wiper arms all back where they belong. Remove the plastic cap from the base of the wiper arm. You should see a nut. Using a socket wrench, tighten the nut down. Put one hand close up on the socket wrench, close to the socket (like choking up on a baseball bat). Use all the strength that just one hand can apply, choked up. If you use two hands or if you go far out on the wrench, you could apply too much force.
