How's it going guys, my wiper switch works halfway the timer part doesn't work but everything else from it does. Idk if that makes sense. U guys have any idea what it could be that made the timer stop working? Could it be a relay or maybe the switch just stopped working in that department? Thanks.

 

Could be the actual wiper control handle.

 

I agree with the above. The timer-control is in the switch assembly in the steering column.
