The brake/turn signals left and right side are not receiving power at connector for trailer-running lights, trailer brakes work as well as aux.

There are 2 relays under the hood. One is for the right side and the other for the left side. There are 2 fuses under the driver side panel. Remove the panel and check fuses #6 and #38. If bad replace. There is a service bulletin on diagnosing this problem but I would need a fax number to fax you the info. For now posting picture for the fuse location. So it will be F2.6 and F2.38 Let me know what you find and if you want the service bulletin will need a fax number to fax. Good luck and let me know how it goes.

OK BOSS

In order to get this diagram from "Prodemand" I had to make 3 screenshots, then crop 'em down.

This is "Exterior Lights"

Prodemand sorta is a rent/ subscribe repair manual, but here at 2car, we have permission to sorta take some of this info and post it on here to help people. Hence my inability to copy the diagram in one chunk.

You can also find/ buy manuals on our site if you will surf a little on the home page

I INSURED THE PIECES OVERLAP AND THERE ARE NO MISSING PARTS- THE FIRST IS THE TOP, THE SECOND IS THE MIDDLE AND THE LAST IS THE BOTTOM.

If you print these, they should fit right together with some overlap

Locations of things are labeled, fuses labeled, etc

You should see things you need beginning at the top of the 1st diagram

I'm more of a Jeep Guy - things with a carb, so much of this modern over engineered stuff is not my cup of tea! I am sorta good at researching stuff.

Other fellers on here are good about jumping in with info too!

LET ME KNOW IF THIS HELPS OR YOU NEED OTHER DIAGRAMS (if I'm able)!
