Hey everyone. Long time reader, first time poster Lovin' all the great advice and help everyone contributes here - it's been super helpful!

So, I installed a new wiper control arm that has extra features that my old one didn't have (like a delay selection knob ans press up for spray/quick wipe). The switch works the basic wiper functions, but the new features don't work properly.

Is there any wiring or relays that I'm missing, or is the circuitry for these extra features inside the wiper motor itself?

Yeah, I know it was a long shot to think all the magic was in the switch... Thanks!

Did you ever figure this out?
