This may help. I have a '99 Suburban which most likely has the same wiper system. Mine was completely berserk for some time. Would not start when turned on, then later started and would not turn off, would not respond to speed changes - absolutely nuts. Nobody could tell me what was most likely. Consulting forums like this one, I learned of the circuit board on the wiper motor. Easy to change. 10 minutes or so. I think it's called a "wiper module". Found many sources on line from $25 up. Dealer wanted at least $75 for it. Local parts house has them for $35 or so, no waiting. May be the answer. Dealer wanted $75 just to check it out.

The first place you may want to start looking is the wiring in the steering column if the windshield wiper controls are on the steering column, or behind the dash if the controls are on the dash.
