Hello and thank you for your question,

There is a known issue with the type of problem you are having with the light and the wipers and it usually caused by a damaged Smart Junction Box due to water intrusion . In order to determine if that is the actual case you are going to need to do some testing, I have enclosed the steps in the link below, copy and paste the link to your bowser to open the steps.
