KW Dash Lights Go Off - NOT the dial

my 2011 700 has done this twice and came back on
hasn't happened in about 9 months

 

Our older trucks with the new-style dash have started to show this problem and it turns out there's a control module that goes bad.

 

if your relay got hot you have a wiring problem somewhere more than likely. something is making that relay get hot. a bare wire somewhere shorting out more than likely.

 

My 2010 w900 had same issue, went to KW dealer, ECM needed update fixed the dash lights and a cruise control issue.

 

I found that on mine with the older style dash, I would get a flicker then my speedo lights would go out. Then again on my Rpm gauge. I replaced the lights and more importantly the sockets, and have not had the problem since.
Hope it works the same for you, as it's a cheaper fix.

Cheers,

*Edited* Sorry, didn't read the first part about it being a 2013 unit.

 

On the 2007 and up KW's the dash lights, interior lights are controlled by the cecu, the computer behind the cup holder. Some times when the lights go out if you pull the 3 fuse's labeled cecu, let it sit for a minute then reinstall them the lights will come back on. should be two 15 amp and one 5 amp.

 

My solution was the turn signal stalk on the steering wheel

It seems the power for the dash lights and gauges goes through the turn signal mechanism on the steering wheel

I had the following symptoms

Dash lights out but speedometer and rpm gauge worked

Gauges did not cycle when key turned on

Info screen above the speedo and rpm gauge worked but the select wheel would not change the information

Turn signal bar loose.

How I figured it out was the cecu 15 amp fuse was blown. It sat for awhile with the fuse out . Replaced the fuse and all worked but the lights above the lights, cruise, etc..

Opened the door and pop. Closed door, replaced fuse. All back on

Giggled the turn signal bar and pop. I was told back when that the light power was routed through the turn signal bar so I immediately released that had to be it

Replaced the turn signal switch, replaced fuses, all works again

Update... fuse popped again going down the road. I think I am going in the right direction. If the truck is stationary and no problem it's gotta be a loose wire that vibrates and shorts going down the road.

 

Had it happen a couple times on my back in 2011. Did have a rain leak dripping down on the dash and soaking into the defroster vents for probably a year before I bought the truck. Had it in the shop for some other work but when I pretripped the truck before leaving the dashlights were out again and had them rip into the dash and fix whatever before I would leave.
