04 955 S Electrical Short Please Help!

Hello Everyone!

So, my Sunroof, Rear tail lights, brake lights, rear hatch, and rear wiper will not work.

Reverse lights are stuck on, vehicle will start without pressing the brake.
Vehicle runs fine, just cant drive it due to the lights not working.

Had some rain, So I'm thinking it's a bad connection somewhere.
Fuses all good (all of the problematic things are located in one strip of fuses in the fuse block)

Removed cover and inspected rear wiper assembly, no bad connections Removed the drivers seat, inspected for any water damage or bad connections, fuses good.

Sanded and re-seated all ground wires that i stumbled upon, (they were all good, just gave them a quick scrub and reassembled)

I've read something about a rear convenience control module, cant seem to locate it, does anyone have any suggestions to help me out?

Thanks in advance!!

I also checked my rear battery, voltage was good, nothing out of the ordinary.

All those systems you report as faulty are comtrolled from the rear comfort systems control unit.

Left fuse box on left side of dash has fuse number 53 which is 5 amps and powers the control module. Check the fuse.

The ground point for the control module is near the right tail light. Check it.

The control unit is located behind the rear right access panel in the rear cargo.
Try reseating the electrical connector to it for a possible fix if the above do not resolve your issues.
