Cascadia Turn Signal Problem

Do you have an owners manual? Would have left the dealer without it.

 

No I don t but I think it's the relay but I don t know where in the truck to find it

 

So my wipper my headlights and my turn segnal and also my bunk lights too they stop working all at once today do any one knows where to find the relay please

 

My 2012 manual doesn't show any relays or fuses for any of the items you listed. I think no relay or fuse for headlights is strange, so I'm doing some more research.

 

Do the high beams work?

 

I would start by removing the glove box (4 - #25 torx) and check/reseat all the fuses/relays and connectors.

 

I did that but get nothing the runing is on you know in the headlights and maker lights at top of tractor all so works too I was planing to take it to Freightliner in the morning but I wanted to see if I could fit it myself you know they may charge me a lot that's what afraid of dam I did not sleep knowing I just drive my truck all the way from Texas and everything was ok and now it's doing this thank you for looking if u find something let me know

 

Also it make my check engine light come on and stays on

 

So far it looks like they're going to have to hook it up to a computer to get anything out of it.

 

The troubleshooting manual says they are "unfused logic controlled outputs" on connector X18 which connects to the SAM Cab behind the glove box.
