My track pad works 100% perfectly but it will not click, which makes it a little hard to work out where i am supposed to click and take a bit longer to work out what i am doing
Open the MBP and check for swelling of the battery which resides underneath it and may be interfering. If this is the case the battery will have to be replaced.
Otherwise, make an appointment at an Apple store genius bar and see if they can restore the 'click'.
Try cleaning around the edges of the trackpad
Also check your settings >Sys Pref>Trackpad and see if something changed.
>>point and click>tap
