Two Mechanics report about a pilot reporting the window wipers on their CRJ-200 were running on their own at the gate. First Officer's wiper control panel was wet inside the cockpit. Aircraft was ferried to replace leaking window.

Narrative

I was called out to aircraft with a gate call. Pilot reported window wipers were running on their own; without the switch turned on. I went out to troubleshoot and found the First Officer's wiper control panel was wet on the back side. I was advised by my Supervisor and maintenance control to isolate the leak. I removed the trim on the First Officer's side of the flight deck to find the leaks. I noted leaks in multiple places; and informed maintenance control. After a few hours of back and forth; maintenance control telling us to pull the windshield without a hangar and in the rain and what not; they finally decided to get a ferry permit. I asked my Supervisor and maintenance control if I needed to document any of the work done with the trim/windshield control panel and was informed no. I asked what to do with the trim pieces and was informed by my Supervisor to store them anywhere on the plane; as long as we didn't block an exit. Maintenance control stated that they wanted the new wiper control installed in the plane as well; so I did. Maintenance control had me fax the log page with the original write-up and the next blank page. I did that; and they wrote down the signoff for the item on the log pages. I was informed to copy everything down; as written then sign it off. I was then informed that the airplane was 'good to go.' I copied everything down then signed it off. We received the ferry permit; put it with the logbook; and returned to the plane. I stuck around till the pilots showed up; answered all their questions and watched them take off. Cause: Because I did what I was told to do. It was my understanding that the ferry permit covered all work done; since it was still broke. Supplemental information from ACN 823525: An open discrepancy was faxed to ZZZ1 to be signed; which I did sign for the aircraft to be ferried from ZZZ1 to ZZZ2 to fix leak.
