The wipers won't always start when turned on or stop when turned off. Sometimes run in a non selected speed or just stop in mid stroke. This is obviously a problem in the control circuitry.
My question is where is this circuitry located?

It's the wiper control module. It's attached to the wiper motor on the firewall with three torx screws. GM issued a recall on these wiper modules involving almost 2 million vehicles, so you may want to check to see if yours was involved in the recall.
