Thanks OP for this quick fix! I had the same issue after raining and cold weekend. I will be cleaning and adding lubricant on the seal as well just to be safe
Taking to dealership on Tuesday. Driving through mild rain today for approximately 3 hours. System, parking and headlight malfunction notification came on. I tried negative battery disconnect for 30 min but issues persisted. Pulled codes from OBD and only had loss comm with BCM (U014087)...
