Wiper Problems

I have a 1990 Olds 88, and I'm having trouble with my wipers. Last winter they got messed up trying to clear some snow from the windshield. I don't know if it's the motor or the switch. The wipers do run, the problem is they won't shut off unless I pull the fuse. In the Off position, the wipers run continuously. Intermittant positions, the wipers do work for a few minutes then stop. Continuous positions, they work. My big question is, would this be the motor or the switch? I'm getting tired of fighting with the fuse while driving. Thanks!

Welcome to AF.

Its your switch.
If they run continueously when off, then I'd say the motor is fine.

btw sorry someone didnt get to you sooner .
