Rear door open alarm

Had a constant rear left door open . checked the wires to the door locker switch (Red, Green/yellow ) tried to short them , as expected that it should worl on Normaly closed . would not solve the problem . disconnected the plug with wires from door to mid frame , and problem disapeared .
I could not beleive that the door close is checked by "Open " switch .
Cut the green/yelow wire. and problem is solved !!!!!!!!!!!!!

No much surprise for Franch cars electronics !!!
