The wife drove though standing water this week (flooding here in S. Michigan). Now the driver low beam (LED?) is not working. The passenger headlight now stays on for approx. 15 minutes after the ignition is shut off. I can unplug the driver light pigtail and it shuts off the passenger light (with the ign off), but as soon as I plug it back in, the passenger low beam comes back on! I don't see a means to replace the LED bulb for the low beams, wassup??
