Hi and Thank you for help. I have rechecked the wiring, I even took of the inside plastic covers to see as much of the cables as possible. No more cuts of insulation were visible. I also rechecked my previous taping, it all looks good. Cables are completely separated and the cuts covered. The cuts seem to be like from a knife or sharp object, but definetly not from burning or heat (have not seen any heat/burning related damage anywhere). The cables look healthy, apart from those cuts. They are in the area where the rear door is attached to the back of the car (wagon) - the cables exit the door and enter the rear part of the car. The insulation might got cut by repeated opening and closing of the rear door, although they run in a rubber envelope which looks untouched.
I also checked all the fuses. They are OK and of proper size. It is a big puzzle. Thanks a lot for help.
