Replaced Trackpad Not Working

A few months ago after wiping down my Trackpad it started acting crazy, then became unresponsive except for random jumps across the screen.

I ended up using a mouse until recently when I ordered a replacement trackpad but after getting it put into my computer it doesn't work at all. Doesn't click nor does the mouse move. After contacting the seller to double check I got the right trackpad for my computer I returned it and got another one hoping it was defective. I just installed the replacement and same deal, it's like there is nothing there.

I double and triple checked my settings and everything seems to be set right. I restarted the computer multiple times, once in safe mode, my battery is fine (replaced about year ago after it ballooned).

I'm kinda at a loss of what to do, is there another component to the trackpad that doesn't get replaced when you get a new trackpad that could be messing it up?

Thank you!

Yes, I replaced the ribbon!

Watched a bunch of video how to's, doesn't seem like there is much to it as far as installing it and it was easy to do.

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

If no success try resetting the SMC http://support.apple.com/kb/ht3964

Did all that too.

About the only thing I've found that I haven't done is uninstalling the OS X and reinstalling it, but I'm saving that for last resort with a decent chance it would work.

Hi. I had that problem once and found that in changing the track pad I did not get the ribbon cable seated right. Had to go back in and redo it.Also if you have the original ribbon cable and reseating doesn't work try that cable. You could also repair permissions, long shot but worth a try. Do you have any bluetooth devises running? If so try turning off bluetooth.

Tried switching the cable like you said but nothing change.

Then, I took it apart one last time and put it together and now it's allowing me to click (still seems sluggish and doesn't work everytime though) things but still no mouse movement.

Hi seems like you are starting to get somewhere. Could it be that you original trackpad was good and it was the ribbon cable? You could try cleaning the ends of the ribbon cable. I use an eraser for doing that. Then lightly with a soft cloth.
