Helllo, Last night i bumped my apu fan with the trailer

The fan on the rear of the sleeper (radiaotr fan) does not come on. The fan bades were sslightly wedged when inspected. I freed them, disconnected the fan and cond connected it directly to my batteries and it works fine. I reconnected the fan, still an ACS code.
