Default Multifunction wiper switch broken?

On my 2011 WRX I only have one wiper speed. Full blast. The washer nozzles spray when I hit the button, but it doesn't wipe. I have no mist function and the wipers also do not park. I have to time it perfectly so that it kind of looks like they park.

I can go get a multifunction switch from picknpull to rule it out, but from what I have searched, this could be related to the wiper motor or possibly the alternator. My guess is the switch. Any help is greatly appreciated.

The only interior mods are aftermarket head unit and accessport.

I would guess wiper stalk
Good bc that is cheapest ‘test’ out of your other choices

B4 you buy one
Take that sucker off and look at all the connections
Pretty sure they are 5mm wide copper....plugs right into a pigtail on the steering column
Possibly corroded
If everything looks ok inside
Unplug the wiper motor pigtail.....inspect as well

Thanks for the advice! I'll look at the connectors. I'll probably just go buy the switch at picknpull, that way I have experience in taking the dash apart to get to the switch and motor. Might get the motor too.
