No blinkers/brake lights on trailer with OEM hitch

-July 2012:
---Purchased vehicle and OEM trailer hitch
---At time of purchase, OEM trailer hitch installed
---Had never tried to use hitch, until …

-17 Apr 2013:

---Went to U-Haul to get 6x12 trailer for move this weekend.
---When U-Haul tried to hook up the trailer, the following happened:
--Lights on the trailer work fine
--When turning on blinkers, blinkers on trailer do not work
--When applying brakes on Jeep, brake Lights on trailer do not work
Note:
---Brake lights and blinkers work fine on my Jeep
---U-Haul confirmed the trailer lights (brakes/blinkers) were working with another vehicle/tester


Any ideas??

Re: No blinkers/brake lights on trailer with OEM hitch

Easy Fix,
Unfortunately it requires a trip to the dealer though.
They forgot to enable the trailer wiring in the PCM when they added the hitch.

Since the dealer installed your hitch they should do it for free. I installed my own hitch and the dealer charged me $30.

Re: No blinkers/brake lights on trailer with OEM hitch

Dealer just called, said the code was in the system for the blinkers, but it didn't take. They re-flashed it and they are now working. No charge.

Thanks kbre for the help.

That's information that is new to me, and I'm sure a lot of others. I would have thought something with wiring.

Thanks for posting.

NP but actually, it's not new info, I found it using the search feature here in the forum when I bought my GC and was thinking about a hitch for mine. Thought I would save newtoncd8 the trouble though. Vast amount of info in the archives here, just have to look for it.
