Cascadia electrical nightmare

Hi all,

Have a 2013 Cascadia, couple of days ago I had to replace the truck batteries, replaced and thought all was well. Not so. I have no fault codes or at least none that I can read through the display. But, my high beams don't work, wipers and washers don't work. My turn signals don't work if I put the stalk switch in the high beam position. Also the blue high beam indicator will not light up either. Everything else seems to be OK. Any help would be appreciated. FYI, I did try to crank the truck several times before deciding that I had to replace the batteries and the amber CEL was on at that time. After replacing the batteries the light cleared on its own.

 

Thanks Brandt for the reply. Any fuse or relay in particular?

 

thanks mhyn, I will do that today and let you know how things turned out.

 

Ok. I just got to the truck and is has a fault code. SFU 49 SPN 523544 FAIL 31. I've turned off switch and disconnected the positive cables. Now waiting 30 minutes.

 

Your suggestions are done. Still same results. Disconnected stalk switch and the control with the hazard light switch on it. Reconnected with power on. Turned kill switch off an on now everything works. My main AC did not go off when I shut the truck off. I had to turn the knob to off. I think that subcon may be bad. Your thoughts.
