My third brake light leaked on the previous owner, I have some water stains to prove it. It seems he must have fixed it because it has not leaked in the time I have owned the truck. 

 

Winter here in Western NY.

I think you may be on to something with the cold weather. I did notice it started happening repetitively once the temperatures dropped. 

 

I still need to order the control module, but I would also like to order that connector and do both of them. Just cannot seem to find the connector online or even a part number. 

 

I do think that my issue is from the control module. Either water got in, or it just failed on its own. 

Stains may be able to be removed with distilled water and a microfiber towel. Dampen the towel and wipe the headliner lightly. Keep at it, one direction only (towards the edge). If nothing else, you should be able to at least lessen the line showing how far the water wicked into the headliner.

 

Occurrence of the issue for me is like 10:1 or 20:1 of cold weather versus not. I could easily replace the control module, but I don't like throwing money at electrical problems because they get expensive very quickly. Prove to me it's faulty and I'll happily replace it...

I will try that distilled water trick. 

I haven't tried much to get it removed because I didn't want to make it worse. 

 

Once summer comes and I start towing again, I might just have to start throwing parts at it.

Just don't over-saturate the headliner as you could cause the fabric to separate from the base and then it would need to be re-glued as well.

 

You could also possibly get a detailer or body shop to guide you on a way to make it better.

Ended up pulling the trigger and replacing the Trailer brake control module under the bed by the spare tire.

 

Solved my issue.

 

Thanks for all your input.
