My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

return it to Ford for they have the job warnatied and will repair fro free. It is better than ripping back into it to find the issue.

Is there a note on the invoice that they programmed the truck and the body module? Did they put the revision number on there? This sounds like they skipped a step when they did the repair or there is a loose wire that they didn't address. Either way, it is now warranty covered for the comeback repair on it.

The cargo lamp is working some of the time. Some one else told me it was the sjb module,so I unplugged one of the wire harnesses off of it and plugged it back in, then the cargo light works part of the time. If the cargo light quits working ,I just unplug that harness again and it starts working again. Is the sjb bad or do you think it's a wire harness issue?

It sounds like the junction box. If you can wiggle the wires at the plug and the wires are good, then replace the bulb. The junction box can see a issue with the resistance in the bulb at the socket and will shut the circuit down. So do that first and if the issue continues, scan the junction box to see if it is showing a lighting code. If no code, then the junction box itself is acting up.

Most times it is the bulb or the socket for it.
