Nikon D5000 DSLR autofocus not working?

The auto focus on my camera has recently not been working. I don't recall dropping it or hitting it against something and if it happened it was just a slight hit and a while back. The camera does not focus not matter what mode its on, but it still takes pictures they just come out blurry. Is there any button I could have changed to by accident or pressed? Please help me I'm so upset, I hope it doesn't need repairs because I can't afford a repair.

Is the AF/MF switch on the side of the lens set to MF (manual focus)?

Remove the lens and make sure the contacts and mounts are clean and free of debris.

Make sure the auto focus switch on the lens is set to auto and not ike halfway bewteen manual and auto. If it is switch ti to manual and then back to auto.

see if that helps. If it doesn;t try another lens if you have one. The auto focusins motor may have broken.

I guess that you have read your user manual and discovered that you can place the lens into the manual mode two ways. On the lens and on the camera.

If you changed the shooting mode from auto-focus to manual-focus and it was accidental, then you need to spend more time reading your user manual.
