trailer not connected,yet connected

[Wolfman00]

yesterday i went to hook up the car trailer, all lights work, brakes worked… but nothing came up on the dash about the trailer being connected as it usually does.
a few things- trailer plug looks beat. could be that.
bad ground cause it?
last time i used the trailer i had to jiggle the plug and it worked.
worked fine with the camper last time i used it so i dont think its the truck.
ideas where to start looking?
trying another trailer today after work too.

I vote bad ground. every time I tow my boat I need to mess with the ground connection on the trailer. it's usually clean with no rust but it just doesn't like working most of the time

it’s annoying, but always seems like 1 out of 3 trailer uses i gotta jiggle some sort of wire!

do you have clean contacts in the plugs?

I had this issue and found the gel type insulation in the plug itself was deteriorating and coming out, this was actually allowing the back of the terminals to contact each other and cause the faults. Dealer installed a new trailer plug under warranty - no more problem.

do you have clean contacts in the plugs?

all started when they changed my battery. is there something that could have been turned off in the process?
im pretty pissed off at the bullshit this truck has.

Try this

battery isnt the issue, i think when it got replaced some functions didnt come back. unless that restores it?

 

[Wolfman00]

went to dealer and they confirmed trailer connects and works, but the trailer does not connect in the software. so it goes in on friday.
