Hi, I am new in this forum and I have the exact same problem. I have ford focus mk2 year 2005. This is my second car. I used to have the same focus but 2007. But I crashed it and now I am selling it ofr parts. About the problem. I have replaced the motor with the motor from my old car that is 100% working and the result is negative. The wiper stops wherever it wants to. I checked the cables in the rubber housing between the trunk and the car but everything seems to look good. The only thing that left is the build in "indestructible" relay. I someone has any suggestions please tell me I will try to fix it. I am sorry for my bad English.
