If the fuses up front are good and this model Journey is on a Freightliner chassis like mine I recommend you call the Freightliner help line. Give them your VIN and the problem. My signal failure was the Headlamp Control Module under the dash near the steering post. Easy DIY, but a costly part. Hope your solution is more simple.
I hope they took the guy that dreampt up that hiding place, outside and beat him to a pulp. That is the damndest place for the fuses I have ever run across.My 05 Meridian 36G has a fuse panel in the electrical cable compartment. It is behind a large metal sheet that is very hard to see as it is painted black like everything else. My turn signal fuse is in there for the Toad light plug in by the hitch. Might be a flasher unit in there too.
It is the whole aft bulkhead. (On your right as you face the compartment)
