I posted a thread a while back about some wiper problems. Lots of good info in that thread:

Do you have pulse/intermittent wipers? My 87 S10 had the same problem and I replaced the pulse board. Back to new. Its considerably cheaper for an S10 though.

It may be the actual stalk. Which are also expensive, and somewhat hard to find in chrome with cruise and delay wipers. If you dont feel like further troubleshooting try and locate one for sale from a seller who takes returns and just swap it to see if it works.

The stalk doesn’t control the wipers. The stalk pushes into the wiper switch that is in the column. It is the pivot that works the high beam rod and has the turn signal switch link hooked to it.
