Drupal 7: Local site URLs all point to production site
I found the issue.

If you're using the module "Domain Access", the uninstall hooks do not work properly (or at least they didn't on our site).

You'll need to go into your DB and change the domain settings after you've disabled your module. 

All of the Domain module tables that have your production (or old URL) in them need to be changed. Removing those tables will likely corrupt your DB and make the site unusable.
