Exterior Trailer Light Problem - Need Urgent Help

Was scheduled to leave tomorrow for Arizona

2018 JAYCO 321RSTS

Hook up to truck and NO left side lights, Fuse in truck popped.

Also popping fuse for tail lights.

Acts like a dead short some how only affecting left side. Any suggestions to track down the issue.

Does anyone have electrical schematics for this model.

All help appreciated.

Thank You

Take out the bulbs on the left side and re- insert them until you see it blow another fuse. Short will be in that socket or section of wire

Is there an electronic module in these units that controls the side marker lights so they act as marker lights and turn signals?

Not sure if your rig has a sealed bottom. On my unit the factory did such a poor job running wire it got tangled in the slide linkage causing a dead short, see if you can follow the harness
