When the weather was very cold my boot lid stuck whilst opening, just once, and then worked properly again the next time. However, now the load cover doesn't lift up automatically when the boot opens. The lifting mechanism just does nothing. I am wondering how complex the mechanism is and whether I am in for big costs if I put it in for repair. Not having it working is not the end of the world. Does anyone have any advice on the cost of parts for this to help me decide whether to try and get it repaired?
