Hi all,

New 100 series owner here. My windshield wiper controls on the right hand stock have completely stopped working. Both front and rear, and the washer controls for both. I’ve checked my fuses and they are all fine… I have had leaking from both of my A pillars, and the issue started when the leaking did. I’m assuming it’s a relay issue with the wiper controls, but I’m at a loss if that is the case. Any help is much appreciated!
 
Did you check the fuses after removing it form the fuse box or, while it is in the fuse box with a test light? Rusted fuse legs may not pass power to the circuit bord. I'd remove the fuse to inspect any corrosions. Also check the relay legs as well.

Checked them after removing and replaced them for good measure, still no luck...
 
I'm thinking it's the IG1 NO.3 relay, but I'm not sure what else it might control. The below diagram seems to have it just control the wipper system, but I might be reading it wrong...
