Hooked up the trailer today for the first time, i have running lights, right turn signal, and no left blinker. left bulb looks good. dual filament. #6 fuse inside truck looks good, can't figure out why no left blinker... trailer worked fine on my previous truck. Not sure what to tackle next.. Any ideas?

 

Does the trailer plug on the excursion illuminate your test light on the left blinker pin out ?

 

uh... i don't understand your question... sorry. I'm learning as i go..

 

One of the pins in your trailer hookup is for your left blinker. See if it is getting voltage

Here is a rough video from a quick google search to give you an idea. You can use a test light in place of a multimeter if you wish

 

ah.. i get it. Let me put the kids to bed and ill check it out. thanks

 

I believe the trailer turn signals are fused individually. Check the under hood fuse box, I think they are 7.5a

 

Fuse looking good vs actually testing good can be 2 different things... 6 looks to be relay power... As previous poster said, check your other fuses, some fords fuse each trailer turn signal separately.

 

Man I love this website. under the hood, #20 fuse, trailer tow/stop, turn LH

 

Well, i fixed the trailer lights. But now my rear view camera doesn't work. It's gotta be something when i unhooked the battery. I don't have the user manual for the radio(pioneer in dash), so i'll start hitting some buttons....

 

The rear view option on my Pioneer has to be turned on manually the first time after giving it power.

Should be able to download the manual from their website.

 

You're correct sir. had to find the camera setting, then change polarity of camera to battery. fixed. Thanks for your help.
