Default [Q] Trigger Messaging app auto-delete?

Hey, all

I'm running Cyan M9 on my phone and trying to thin out the 50000 texts I have on my phone. Basically, I want to use the stock Messaging app to auto-delete old messages, got it all set it up, but it's not doing anything. Is there a way to trigger the auto-delete process to start? I'm way past the limits I have set up.
