Hello! With my W202 the climate smells at extremely high outside temperatures (rubber-fishy). In addition, the windows are fogged when it has stood overnight in the garage and the climate is not on. Does speak for residual condensate. I have already found the drain hose in the transmission tunnel. Also comes out water. Climate cools well. Can you clean the system yourself without having to disassemble the entire box? For example by flushing over the drainage hose? Or m It is such an air conditioner cleaner from Liqui Moly? Where do I stuff the hose from the can? Does anyone know? Would you be very grateful for your help!
