Locking beep/flash gone help

All of a sudden my truck doesn't beep and the lights don't flash upon locking. It still does it when unlocking. How do I get the beeps/flashing back?

 

Owners manual

Mine did this the other day but was due to one door not being closed completely. I closed the door and voila, beeping and flashing came back. If all your doors are closed then maybe a door switch went bad?

 

I will check the doors first, then the manual. Thx

 

Thank you guys, figured it out. Apparently my real door wear my son sits, the lock wasn't locking. I am assuming it was dirty, cause after playing with it for a bit, everything is working again.

 

oh good, that was nearly totalled.
