Wind direction not working

my wind direction was working and now its just showing north all the time can any one help

Ted, First, what kind of weather Station do you have?
I assume that you mean that WD is showing North all the time. What does your Console(weather station) show? Are the batteries good? Does the wind speed show?Is the arrowon the anemometer actually moving with the wind? T^he more info that you can provide, the easier it will be to help you.
