my golf has a ghost problem
 

every time I turn on my car my blinkers and dash light light up and my wipers come on constantly if I pull my brake it stops or sometimes my back wiper button will make it stop..my ligts and blinkers dont work when this is happening also..I have had all sensors check and took it to a shop they said they can't find anything ! I'm so frustrated any thoughts on what it is?

I firstly clear it that I am not quite sure about this thing, but I guess that there might be an internal short circuiting among the controls mounted across the steering through which the light, blinkers and wipers work out. Other than that as such I do not find any sort of problem either from the battery or from the other sections through which this problem is happening.

My turn signals and hazards don't work when I hit the breaks. :(
