Troubleshooting Left Trailer Light Flashing for Both Left & Right Blinkers Behind 2020 Dodge Journey

Question:

Will a #S0634M-RA # on unit work on a 2020 Dodge Journey. Having Trouble getting the right signal to flash. When I turn on the right signal the left Trailer light blinks. When I turn on the Left signal the left trailer lite works like its supposed to. WHY

I think you are referencing a sticker number found on a Curt 4-way connector. Unfortunately this number does not tell me exactly what unit you may have on your 2020 Dodge Journey. I do see we have the Curt T-Connector Vehicle Wiring Harness for LED Taillights # C56330 and for Incandescent Taillights # C56109. These are specific to the style of tail lights on your vehicle and not the trailer you may be pulling.

It may be possible the powered converter on for your 4-way is damaged internally and this is what is causing only the left trailer lights to function. I do recommend first using a Test Light # PTW2993 to test the 4-way and the wiring going into it. It could be a malfunction with either the wiring on your Journey or the trailer as well which is causing your issues. A simple short in the wiring on either could cause the same issue you are having.

Please let me know if you have already checked the functions with a test light and I can give you more exact steps to follow to verify exactly what is going on and what may need repaired/replaced.
