I have a 2011 GT convertible. I retrofited the 2014 cluster and shifter and added oem nav several years ago. I damaged the SJB in the door and replaced it with a used one also replaced the pig tail to the large connector since the connector plastic fell apart this was done over a year ago. I drove the car for the first time this week after winter storage and everything was fine but the one day I noticed the cluster went dark for a split sec then came back i thought it was just me so everything worked fine for the next few days. Yesterday the radio went off, the tpms sensor light came on, the door open light came on and so did the brake light and the hvac stopped working. the car was still running fine. Is this a connection issue or a SJB issue. How do I narrow down the issue?

I would Check The Connections at The Mentioned Points You Worked on Previously. Especially Repaired Pigtail Make Sure All Connections Are Clean & Tight. All Pins Pressed in tight. You Did Not Perchance Pressure Wash any Area's Which May Have Been Exposed to Moisture Underhood??

I would Also Check the Door Drains and Make Sure They are Not Plugged. Moisture in the Doors Could Cause Issues.

A 30 Minute Battery Disconnect Would Reset All Modules as Well. I would Try it.

I Use This Product For Electrical Connection Cleaning!
