trouble shooting trailer wiring harness
 

Hello All,

I am having a problem with a 2004 Pacifica trailer harness. The brake lights work on the vehicle but not at the plug. I am making the assumption that the harness combines the turn signals and stop lights. Any help would be appreciated.

Thanks

did u use chryser wire harness or aftermarket one?

The harness takes power directly from the power distribution box in the engine compartment not from the brakes/turn signals so they can work but they willnot trigger the trailer lights if the supply fuse is blown in the PDM. Check for a blown fuse #10.

Yes sir, it's a Chrysler harness. The numbers on the tag read 82208221 and 23489A if that makes a difference. Using a test light, I get power for tail lights, one with constant power ( don't remember which one) and both turn signals but no brake.

Thanks

Checked the number 10 fuse ( blue 20a) and it looked good and has continuity. Anything else I should check?

Thanks
