12 Volt Freightliner Electrical Relay?

[webmrkt]

Mechanic shorted out my system and I can not find any kind of relay switch?

I lost Windshield wipers, Radio, Heater/AC, Visors, Backup Camera, 12 Volt house gauge. There must be one relay that connects them all together. Since it is so many things I am pretty sure it can not be just one little fuse.

Any help greatly appreciated. 2004 Freightliner, (national 39' Tropi -cal) Where or where do I look?

I had a problem locating the fuses for the dash area of our Pacifica and asked a question along the same line, never did get an answer until I posted over on another site. The fuse blocks are at least on our coach in the front driverside basement bay along with the outlet for the air compressor, and landing jack mechanical.
Good luck, hopt this helps

As an after thought, if you check things out, and these items are not on a relay, check the ground to the appropriate fuse block.
