Hey all. I have a 2013 1500 RAM Sport (LED tail lights). In the last month I originally received a 'Right Rear Turn Signal Light Out' message. It was intermittent at first then more frequent. It seemed like the tail lights were working properly (checked with turn signal on and hazards).
Then I started troubleshooting a little more. after reading as many forum posts as I could. I swapped the tail lights to see if that changed the message to the Left.... and it sort of did. So now I get the 'Left Rear Turn Signal Light Out' message even though I have obviously put the lights back on the proper sides.
The Passenger side puddle light was busted so I replaced that in case that caused the issue but nope.
I've checked and replace the third brake light bulb just to be sure and no difference.
I've checked the trailer plugs/fuses.... that is all fine.
Both LED Tail Lights have all the LEDs working (low and high, all rows/columns, etc.).
So here is more detail with what is actually going on now that I have troubleshooted (troubleshot?) as much as I can.
1. The message comes on when using the LEFT signal now the first time after engine start and the indicator and the left puddle light flash quickly to indicate a problem although the Front & Rear signal lights were flashing normally.
2. When the Parking Lights are OFF.... the signals work properly on each side.
3. When the Parking Lights are OFF ... the hazards work properly.
4. When the Parking Lights are OFF ... each signal/light works properly with the Brake Lights ON (pedal depressed).
Here's where the fun starts....
5. When the Parking Lights are ON (with or without Headlights).... the Hazards work properly (with or Without Brake On).
6. When the Parking Lights are ON (with or without Headlights).... Right Signal works properly until you press the Brake then the Front & Side signal continues to blink but the Tail Light stops. (Third Brake Light & Left Brake light work normally).
7. When the Parking Lights are ON (with or without Headlights).... Left Signal works properly BUT the Right Tail light signal also flashes (like hazards) but the right side mirror and right front signals don't blink (as they shouldn't when the left signals on/blinking).
Sooooo.... everything works fine as long as the Parking/Running Lights aren't on.... but I do need to drive the truck in the dark so it's kind of a problem.
What the Actual EFF is going on here. Ready to pull out my hair if I had any left. Is there re-programming/resetting that can be done on the BCM ? Settings ? I really don't want to have to take it to the dealership where they'll just say replace the $400+ tail light and then that won't be it either.
Thanks for any help/advice.
