No voltage to the left brake of trailer connector

I have a 2003 Ram 1500. All trailer lights work except the left brake. I've tried three trailers and same result. There's no voltage at the truck connector for the left brake. I've checked the fuses. Don't know what to check next. Please help.

Check the trailer connector for loose or corroded wires that come into the back of it. If the light works on the truck then you have problems with the trailer harness.

Trailer light issues


Hi Donald,
It sounds like a wiring issue. Double the wiring to your connector on the vehicle. Also check the wiring on the trailer connector. I have seen many trailer that are wired to ground through the ******, this of course will cause an intermittent ground and flickering lights. you only need four (4) wires... One for a ground, One for running lights, and Two wires for brake and turn - one wire for the left and one wire for the right. You can also find the proper pin wiring for vehicle and trailer on the internet. Cheers. I hope this helps. John

No left turn/brake light for trailer


In the Uk nearlly all trailor socket wiring is done from the rear light wiring of the towing vehicle so I suggest checking the wiring back from the trailor connection socket and also socket, it could be a broken or cut wire. Also will probably find your vehicle a control unit fitted the trailor socket which could also the problem. Find the pin outs for your turn signal on the socket and connect a bulb across this connection and the common earth to check its not a fault on your tralior.

2003 Dodge Ram 3500 left turn signal problems / trailer


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.

I have a 2006 dodge ram 1500. My left turn signal and brake light on my trailer wiring quit working. Is there a fuse for this wire and where is it located


I don't believe that there are seperate fuses for the left and right turn sigs, The trailer lighting depends very heavily on the white grounding wire near the trailer ball hook-up. Check with a test light at the red and yellow wires while someone else flips the switch from left to right if you get power then check back at the left lamp assy. If you have no power there try grounding that assy. base with a big flathead screwdriver if it works then, you need to change out the left assy.Alsocheck and make sure your left turn lights are working on the main vehicle if not try a new flasher, I've seen this all the time where the flasher weakens and will not operate on one side but will on the other. One last thing, The brown wire is for the running lights only. Have someone stand at the rear of the trailer and, with the running lights on use the left and right turn sigs and step on the brake. If ANY of the other bulbs come on weakly at any time or cross back and forth by them selves you've got to rerun the main ground wire to the trailer. Good luck. Dana

Trailer lights


This is the tow vehicle end. The brown wire ( #6 terminal) is the one to concentrate on. It must have a bad connection either in plug at bumper or wherever mounted, or follow it back toward front of vehicle, and will likely have a connector just behind bumper area, or up near frame as well. Best thing is to use a test light ($5-$10) and probe toward front until you get power showing, then work back to plug to isolate. Begin by checking terminal at plug with blinker on, if no flashing of test light, find brown wire on back of plug & test there, and keep going toward front of truck, especially concentrate on connection areas. Understand? If not, get back to me538a5b8.gif

2003 dodge ram lights work on trailer but brake lights


try http://www.etrailer.com/faq-wiring.aspx. They have very good concise information that might help. Check wiring at each light. You can use the emergency flashers and a 12 volt test light to do this.
Make sure each light is grounded well. A loose ground will cause all sorts of problems. Hope this helps. Mike

I found the problem. Talking with a technician from the controller company, we determined that it was a fuse problem. I found that the fuse to the CHMSL was blown.

LEFT TRAILER TURN SIGNAL DOES NOT WORK


I have seen once before that the fuse box was bad on a 2003 Dodge 3500. I had power in and nothing out. We had to replace the box. Not cheap! Hope it is simple like a loose connection though. I think I had to pull the inner fender on the drivers side to access the bottom of the fuse box. Pain in the ****, but...

LEFT TRAILER TURN SIGNAL DOES NOT WORK


I'd get a 12vdc test light if you don't have one already & start from plug, and keep probing back from there. It may be as simple as a bad connection under truck where joined into harness.
