I haveshorted a fuse on my 2004 Durango w/towing package. I can not find the fuse for the trailers running lights. I have checked with a voltage meter the 7 pin plug and all work except the running lights on the trailer. Lights worked for 1 year and now they dont after trying to hook up the 4 pin plug. Can anyone help me with this? No fuse charts anywhere and the service manual is $340 Help!!!

 

Get your self a fuse tester for $3 bucks i'm not sure which fuse it is but its under the hood in the fuse box on the left fender. (it's a mini fuse)
That 4 pin connector is very sensitive i blew mine twice already!
