2011 Jeep Liberty Factory Tow Package Wiring Stopped Working After a Short Circuit

Question:

Used my 2011jeep liberty to tow a trailer at my cabin. long story short the trailer running lights were shorted. Now I can not get trailer running lights to work at all for any trailers on the liberty. Checked fuses/relays inside engine compartment. Liberty has a factory installed trailer tow package 7 pin round connector . stop/blinkers work fine. Any suggestuions.

On the 2011 Jeep Liberty with factory tow package there are fuses for the wiring in location M2 and location M4. If those are good then you can inspect the actual trailer connector and wiring going to it to see if the short caused significant physical damage causing the problem.

If it is neither the fuses nor the wiring/connector then there is likely a deeper issue, possibly related to the vehicle computer. Since it is OEM tow package wiring the best thing to do in that situation is to have a Jeep dealer take a look.
