My '08 GT had a very intermittent problem in the past week or two where the right turn signal would turn on for a few seconds on startup. Now it is on all the time, except when the hazards or left indicator is on. Those work normally. I narrowed it down to the C2280b connector on the SJB and was only able to stop the indicator when the Medium Speed CAN +/- pins aren't connected. It likely saw some water due to some corrosion I saw near the pins. I took apart and cleaned the SJB which showed no indications of shorts, blown chips/resistors/capacitors and no shorts of the pins; just a little bit of corrosion on the pins that was cleaned up. Any ideas on what to do next, bar getting a new SJB?
