Note: My answer is assuming you are referring to Form view since you have not given much detail.
Microsoft disabled this feature on purpose as explained in this support article - You cannot use the mouse wheel to scroll through records in an Access 2007 or Access 2010 form.
The mouse wheel behavior in Form View was intentionally changed in Access 2007 and in Access 2010 to reduce user confusion. In earlier versions of Access, the mouse wheel would sometimes move the scroll bar, or the mouse wheel would move records up or down. The mouse wheel behavior is now consistent and only moves the scroll bar. There is no property to change this behavior.
The article gives a VBA workaround, but it does not mention compatibility with 2013. You will have to try it and post another question if you have problems.
