[QUOTE="FLGeezer, post: 457946"] Weird issue cropped up today on my 2009 JK. Left turn signal started flashing fast indicating a blown bulb somewhere. Rear is fine. Front off. Replaced the bulb (not LED) although the old one still looked ok. Tested it and it worked fine for about 5 or 10 seconds then quit. Rear still flashing. Tried again and before it died I Jiggled the bulb socket/harness thinking to see if it was a bad wire somewhere but it stayed on....for a few seconds. JScan shows code B163C "front left turn lamp control circuit high". Did some Googling and searched here. Not sure on anything. Flasher relay maybe? But rear is flashing. 🤷♂️ Ideas? Thanks. EDIT: Ordered a "Dorman 645-118 Three Terminal Lamp Socket" from Amazon. Will see if that does anything. [/QUOTE]
