First of all hello to all of you out there, im from Switzerland and finally got my hands on Phase 2 Safrane 2000 year 2.0 16v FROM A FIRST OWNER from new

I am have some issues with it, so i hope that someone can help me.
First- my cd radio works just fine, except when i turn off or lock the car radio display is constantly on(only shuts down normally if the fuse is pulled out)
Second one is that my windshield vipers work on washing the wind shield and the highest speed, inteminent and normal speed wont work(sometimes they do, but they oftenly stop in the middle of the winshield)
Hope i spelled everything correctly, looking forward to some help
Greeting to you all
