I don't have instructions, but I had to change on of mine about a year ago. What I did was remove the front lower panel, as well as the back lower panel then you'll have access from both sides. make sure you label all the wires before unplugging (I used masking tape and wrote what number slot the corresponded to), otherwise it will be much more difficult to get them correctly if you're guessing. Let me know if you have any other questions about it.
