Just got myself a slk230k amg 1999..its a Japanese import. Everything works well except for the electric fan. Kicks in if I disconnect the Engine cooling sensor (temp sensor) runs at full speed. Once I plug it in.. Fan speed reduces and then dies. It works at times well.. But sometimes the fan doesn't turn on. I've looked at the forum and I'm sure will get some positive response here. I changed the thermostat.. The sensor as well since I was getting a p0115 error. Any thoughts?
