The problem is.....I can not locate a relay. The fuse block has all fuses-10amps to one 40amp. This is my next quest.
Uncle bubba, I would never hold anything against someone willing to take their time to help me when asked. Thank you |
From what I have found it doesn't look like your gonna have a relay. It's all controlled by the main switch to the rear of the truck.

A replacement factory harness is only about 3 feet long. It's all fed from the truck wiring to the rear. So if you have no power to the back of the truck you have a problem in the truck lights. In the end this tells me that you probably have a grounding problem and just need to clean all the grounds off and smear some di-electric grease on them. I also keep the terminals filled up with this grease to keep them from corroding myself. Wish I could offer more help here.:argh:

Uncle bubba,
I will start at the end of the trailer harness, clean it all up and grease it all up as you recommend....' "Wish I could offer more help here.'' I owe you much, thanks again! |
Did you get your trailer lights fixed?
|
No, the promlem is in the fuse box. The trailer fuse blew about a month ago. That fuse was replaced and the lights never functioned correctly after that. The wiring from the trailer plug all the way up to the fuse box is in tact and grounded.
I took the apart the fuse box and I believe the computer board inside was damaged when the fuse blew. I thought the fuse would have prevented this from happening. I will take the truck to the dealer this week. Many thanks to you and uncle bubba for the help, it is much appreciated. |
have you tried pluging the trailer into another truck to see if it's the problem?
|
He said he didn't have power even to the trailer hook up. I'm hopin he comes back and gives us a status report. I'm still curious to know what it turns out to be.

I did start at the plugs.
There is power to the plugs, both circular and straight plugs have power going to the running lights, neither have power going to the signal lights. I have power to the running lights, just no signals or brake lights. just thinking outside of the box here and my post is not to make anyone feel stupid cause i've made mistakes too when checking stuff...... just going back to the basics.... |

dumb question again but did you test the plugs with the brake pedal pressed? if the brake pedal isn't pressed then there will be no power to the plug. if there is no power there after the pedal is pressed then i'd look into the brake switch under the dash that turns the brake lights on. have you changed the fuse that you replaced with another good one? i've seen some fuses look good and be bad before.

Closing this as he was due to use the truck this weekend. Im assuming this is fixed - if not, you are free to reopen it.
