RE: "Service Trailer Brake System" message on Suburban
Might check the wiring near the trailer plug. If there is a short, it may have closed the circuit that the truck checks to determine if a trailer is attached but not all the circuits check out, so it gives you a warning. Particularly if the issue is intermittent.
When the trailer is hooked up, all the circuits connect, so it thinks things are fine and enough juice may be getting back to operate the trailer brakes...so the warning goes away and your brakes work.
Had an issue with our ford where the wire to one of the trailer brakes was chaffed and a strand was intermittently hitting the frame setting off a similar issue.
Okay will definitely check the wiring behind the plug when it warms up this weekend. Thanks!

Check for corrosion inside the back of the trailer connector, on the vehicle side.
Thanks, will do.

RE: "Service Trailer Brake System" message on Suburban
if it is like the silverado, highly likely the problem is the manual trailer brake control lever on the dash. easy peasy to replace and often fixes the problem.
I have replaced the dash's trailer brake controller. Super easy to do. However didn't fix the problem.

"Service Trailer Brake System" message on Suburban
In August during a camping trip, the message "Service Trailer Brake System" came on the dashboard when the trailer was not connected to the Suburban. I checked all the fuses and they were good. I hooked up the trailer to the Suburban and the message went away, the trip home was fine and trailer brake worked fine. Unhooked the trailer at home and the message came back on.
I checked the 7 pin connector in the back and everything looked good. I replaced the OEM Trailer Brake Controller thinking it had to be that thing. After replacement, the message stayed on whenever the trailer is not connected, and the message goes away when the trailer is connected to the vehicle. We have done two other trips since and the trailer brake worked fine each trip.
Hooked up the OBD II reader and there are no codes.
It feels like the Trailer Brake Controller thinks there is a trailer connected to the vehicle when there isn't a trailer? Any thoughts?

RE: Looking for LED headlight upgrade options
After trying different bulbs, I end up replacing the entire headlight with AlphaRex LED headlights. Expensive, I think I paid $1k for them. But so worth it to my aging eyes.

RE: How do I pop this cover off to replace the ceiling light
Got it off, turned out the inside lens pops off, then it's four screws to get the whole thing off, it's only screwed directly onto the ceiling, no box/hole or anything. Pretty cheap construction.

RE: How do I pop this cover off to replace the ceiling light
That looks like a standard can light. Have you tried pulling the decorative rim straight down using both hands?
I tried with a prying tool to pull down and it budged a little but otherwise didn't come loose. I didn't want to break something.

I tried to pry with a prying tool and it feel solidly in place. Tried to twist and it didn't turn either. Need to replace this ceiling LED light. Thanks.
