Clunking sound started tonight when I was driving and turned on the heater to floor/defrost. clunking continued when I turned heater off. continued all the way home. Not sure if it is mechanical or computer malfunction. Can feel the clunk and it is periodic. Faster when heater is on. Slower when off. There all the time car is on.

Could be a door/actuator problem-open it up and investigate that's the only way to find what's going on behind there
