It could be the Stalk but I would be checking the easy Stuff first. There are 3 or 4 Ground wires that are mounted to the DS Cylinder Head and the schematic shows both the Wiper and Pump being grounded there.
If it were me (and I've done this before) I would first pull the Ground wires from the Stud near the Coil and clean each Metal Ring as well as the Head area to assure a good connection to ground. While the wires are also removed, be sure that the metal ring on the end is not broken and securely crimped to each Wire.
I had some weird Electrical stuff going on under the hood once and traced that back to a Broken Metal Ring on one of the wires. Ended up re-crimping a new connector to the wire and it's been fine since. Also use some Dielectric Grease on the connections to help keep them clean.
