WAY TO GO !!! another "great idea" from vehicle manufactures

Test plug again, this time try with marker lights on and signals flashingand see what you have for power now. The exposed pronge is ground,( if this is the plug l'm thinking of.)

Well let me shed some light on this issue. I have the same problem. Trailer connection from truck does not have power to left turn signal and left brake light. I just got back from the dealership and $100.00 labor charge. My problem is the TIPM (Fuse Box for short) and FCM (little silver module hooked to the Fuse Box on the left hand side of the fuse box). $910.00 for the parts and Chrysler doesn't have any in stock. 4-6 weeks to maybe fill a back order. I am currently researching an alternative way to fix this issue. I will let you know.

Check the lug on the truck to be sure it doesn't move when the plug is connected. I had one that read 12 volts when I tested it but would slide in or move when I plugged into it. I replaced the plug on the truck and it solved that problem. Trailer wiring typical is yellow to the left turn/brake light. Does the left brake light work? Do the flashers work? Double check the fuses also... to left turn/brake on trailer. Hope this helps. Mike

Check the 20 amp fuse if it's blown. This fuse is located in the power distribution box on the left hand side by the firewall. If the fuse is okay more than likely your multifunction switch needs to be replaced.

Well you are not ALONE .....my 06 3500 does the same thing. no left turn or brake lite on towing. would love to know the solution before taking an AXE to it!!! thank you jesse

Check the plug on the truck, make sure it's clean. You may have to pull it apart & make sure no wire strands from one terminal, are touching another, via wirestrand or corrosion.
