Hello all

 

My 2011 yeti has a problem that I'm ninety percent sure is a fault with the rotary light switch. If I got hold of another light switch, could I just swap them or would I need some sort of coding or programming so that the new part is recognised by the Canbus?

 

In case you're interested, the lights are on all the time. It's been this way for about a week. The 'bulb blown' warning light illuminates on the dash. Also the reversing sensors don't work. The light switch can be rotated from off to sidelights to headlights but with no effect. The lights stay on, which feels like a failsafe mode. The daylight running lights are off, but the headlamp bulbs and side light bulbs are on.

 

Earlier, I plucked the rotary switch from the dash, and as it slid out, it lit up. I confess that I had not noticed until that point that its illuminations were not working. For a minute or two, it worked correctly, switching the lights on and off, and the reversing sensors worked, but then it failed again, so I'm thinking the fault is either with the switch itself, or a wire (or wires!) connected to it. 

 

Any help would be appreciated...

Similar probs last year, a track on the pcb in the switch will have burnt out, I replaced mine with a Tiguan unit, the tracks looked more robust, it was an ebay job!

And new switches don't need coding.

Thanks both.

 

Ipulled out the switch once again, and found that a wire connector buried behind it, which you couldn't see all of, but could poke with a finger caused the interior lights to go on and off. I showed this to an auto electrician who connected the car to diagnostics, and did that the same dodgyconnector affected whether or not the diagnostics was able to read the car, or whether he got a 'no communication' error.

 

That connector has been fixed and so far all is working. Fingers crossed.
