That might be the case but the problem with my scenario is the rain sensor wasn't showing any errors. In ISTA and INPA it shows it as working fine with no errors. The issue seems to be how the rain sensor communicates a wipe to the wiper motor. Whenever the rain sensor was plugged in I would only get 1 wipe when the wipers were set to intermittent, then nothing after that. At least now I'm getting a wipe every 20 seconds while stopped and every 5 seconds while driving. It would be nice if I can get my stalk wheel working and have a few more manual settings. You don't realize how annoying not having intermittent wipers is until they don't work. Wiping all the time is too noisy and loud so you end up manually wiping every time by pushing the stalk down.
