Select Box Drop Down Broken

Resolved: Wasn’t a script issue. Was a stylesheet causing one block to overlay the feature select block.

So, just discovered my select boxes just broke. I use an add-on from cscartrocks to display product feature filters as select box drop downs. Great module that has been working since February. Now, nothing happens when I click on any select box nothing happens. I am pretty sure it’s a core jquery issue and not an add-on problem. When I disabled the addon the filters display as checkboxes but nothing happens when I click on any checkbox.

Inspection in google chrome Console doesn’t show any errors. What should I check?
