Just had one of those today. Actually, we changed a defective multi-function switch to fix a brake/signal light problem, and now the wipers act like yours, plus the washer squirts until the reservoir is dry. Plugging/unplugging, and switch position makes no difference. The bad switch probably fried the logic chip inside the module.
The wiper module is way up under the dash on the driver's side. Stick your head under there, and behind the fuse box you'll see your signal/hazard flasher. It should be a yellow box with a big plug on one end, mounted sideways on the bottom of the big metal support. A small screwdriver will help pop it off its tab. Note the hole in the tab, and the "nipple" on the plastic case that snaps into the hole.
Above that, on the top of the support are two big plastic modules, standing vertically. The white one closest to the column, facing front-to-back, that's attached to a smaller bracket with easily-accessible screws is NOT the one you want (sorry).
Farther forward and to the left, is the smaller black wiper module, facing side-to-side, with a big white plug on the column side. The module is held in very securely by TWO of those tabs-with-holes, that snap onto two nipples on the firewall side of the module. There's no room to get a screwdriver behind it to go at the tabs, so you'll need to slide a big fat screwdriver from the column side, between the module and bracket, and while keeping upwards pressure with one hand, GENTLY rock the screwdriver up and down to alternately put more pressure on either end of the module to work the nipples out of the holes.
Once the module finally comes out, you can pop a few aspirins, and make an appointment with your chiropractor to have your spine straightened out.
