Trackpad Not Working Properly/No Longer Clicking

[SenileTomato]

I currently have a Macbook Pro Retina 15", and have been having issues with the trackpad. Although the trackpad functions, it functions poorly. The right click no longer makes the clicking sound you generally hear when pressing down on the trackpad, although the left side does. I took the laptop in for repair, but because the trackpad still has functionality, it was not repaired...what a load.

Anyone have any advice on how to fix this issue? Preferably an option that doesn't require taking the laptop apart.

Thanks!
