No right turn signal/ brake light on trailer
RAM 1500 2020 Laramie 52500 miles
I have hooked to a few different trailers and I don’t have right turn signal/ brake light on any trailer I connect to. I have confirmed that the trailer lights work properly with other vehicles. I checked fuse F10 and it wasn’t blown, changed it just in case. Still nothing, tested power at fuse and have power in both sides. Removed plug from the back of the 7 way and tested for power on the green wire and had no power there. Since the fuse isn’t blown any ideas on where to look next?

Did you ever figure it out?

Yes, it was the harness after The plug coming out of the BCM on the frame rail. The harness makes a loop and it runs on itself. It rubbed itself through the look and the wire

I bought something that goes in the four prong plug that one works fine but the I think it's 7 prong plug doesn't seem to work but it works for the running lights on the trailer. So I am not sure for mine lol

Are your running lights the only thing working on the 7 pin?

Yeah. And I even changed out the 7 pin plug on the trailer to see if that would fix the problem and negative and all the wires are hooked up properly I triple checked

Ever since replacing master cylinder, these lights came on, went of after about 100 miles, now back on. All new wheel speed sensors and brakes work fine. Hopefully not the dam dreaded ABS Module.

Solved
RAM 1500 2016 1500 47000 miles
It leaks in the back 2 corners when I get a carwash does anyone else have this problem
Don't know if the third brake light is leaking or the wing antenna on the roof I wonder if it could be the pressure of the car wash

Check and replace 3rd brake light gasket. It was a common problem for some of the 4th Gen pickups
Yes Iam in the process of doing that. Thank you very much for your reply. I hope this works. I also see moisture inside the light.

CommentPush button start not working trailer brake service code popping up
RAM 1500 2013 5.7 hemi 230000 miles
The push button start isn't working, it says that 'trailer brake service' is needed, also a code is flashing for 'four wheel drive needing service', But it won't actually turn over, won't even try and start. I push the brake in, then push the button to start it, and it'll turn the accessories on, I push the button again and it turns it to "run" but it doesn't actually start. The dash just flashes a couple times and then it turns it off.
I'm currently stuck in a parking lot so I'm definitely open to any advice, that being said I've tried...
•changing the brake light switch
•Changing the key fob battery
• doing a "hard reset"(disconnecting the battery for 20 minutes)
•jump starting it
•examine fuses for any obvious damaged ones
