Need help! ABS light on after towing camper. Stuck in campground

[Atbspinner]

Towed my camper about 80 miles with no issues late yesterday. Got in this morning and rolled DS window down and ABS & brake light came on. No instrument cluster and can’t roll window up. Took a short drive and brakes seem fine. In the mountains and need a fix. Any advice is appreciated. Just checked all fuses under hood and disconnected the battery but no change.

Have you checked the brake fluid level?

"Got in this morning and rolled DS window down and ABS & brake light came on. No instrument cluster and can’t roll window up."

Does this mean after rolling down window that the instrument cluster stopped working and the window will not go back up?

You have a blown fuse, or bad relay. Please check the under dash fuse panel along with the engine bay fuse/relay box.
Most likely this came from your trailer harness, or related wiring.

what model rig and year? I can try to look up the wiring schematic

Yes, correct. Just drove around the campground and I’m in limp mode now. Drove fine an hour ago besides stated issues

I’ve gone through all under dash and some of the in cabin ones. Going back through all fuses now

Yes fluid level is good

if you have the owners manual. Look up tail light, stop light, towing, towing relay, gauges, for example if the VSC fuse goes bad the ABS light will come on. Also, how about your battery, All connections tight? While it could be something unrelated. I am focusing on the fact that you were towing. Can you ask someone to help check your brake lights, tail lights, blinkers, hazard lights, include the same on your trailer. There are several 30amp fuses that relate to towing.

There is another fuse/relay panel in the engine compartment.

The attached wiring manual covers to 2007. Also, disconnect the trailer harness to see if anything changes.
Good luck.

If you isolate the systems/functions that are not working. It may be easier to locate the root cause.

All fuses confirmed good unless one of the large square relay ones might have an issue. Not sure how I would know about those from visual inspection. I do find. 10a that I replaced in the wrong “open” spot so the limp mode is fixed. Trying get a mobile mechanic by here later today. I’m outside Brevard, NC if anyone know of a shop to suggest

I have interior lights when I open the door. That is about it. Instrument cluster, ac/radio, windows, lights other than emergency flashers all down

brake lights, tail light off as well?

Just finished checking all fuses in the 3 locations and no issues found unless one of the large relay ones has a problem I cannot see. Not sure what those look like if the go out

Yes. Except emergency flashers

My guess is a fusible link in the engine compartment.

 

[bubfuji]

Fusible link block. Contains a fusible wire. Acts just like a fuse. Fusible wire size is usually 2 wire sizes smaller than the source
Also, a good battery ground is critical.

Does that off the + side of the battery? If so I did check that first. Kind of a flat plastic rectangle box.

 

[bubfuji]

Yes

Nm, just saw your schematic. Yes I looked it over and seems fine

 

[bubfuji]

The big fuses with the clear end, a blown fuse would be smokey looking. Or difficult to see inside.
The fusible link may look intact. You would need to feel for bumps or crunchy bits or discoloration, misshapen (sp) wire

Expanding the discussion. Your alternator has gone bad. Not sure though. Good luck, sorry there is no Ah-Ha moment. I need to sign off.
