Cascadia dash out

Did you put the fuse back in?

 

SAM cab module

 

That’s what was wrong when my horn started blowing , lights flashing, plus wipers going full blast.. That’s when I found out most cascadias have a improperly installed windshield and water leaks into the computers and fuse area. 1 tow and 7,000 dollars later I was fixed

 

Usual culprit is "clock spring" mounted under steering wheel first. Unfortunately must be done with laptop.

 

Find the horn, apply a side cutters to the ground wire, put the fuse back in and keep on driving, that's how I'd fix it.

 

I had similar situation. After rain horn started with windshield washer . I pulled connector from horn. Washer pump worked long and died. I put plastic piece on sam cab module and rerouted wires that come from id lights of roof. I made them to go lower of module then rise up. plus I cut some insulation and water now go strait down. no way to stop the leak but its possible to make water flow changes )))

 

most new freightliners have a cover over the fuse block to aid it the water run off.
