Chimes not working
 

Hi I just got a used 2011 Chevy Silverado 1500 and the chimes don’t work. When I turn the ignition over there isn’t a seatbelt reminder chime and when the door is open with the vehicle in gear it reads on the screen “door open” but there isn’t a chime. If you know what could be wrong please tell me. Thank you.

aftermarket stereo?

No, the only things that are aftermarket on the vehicle are the topper, the trailer brake, and a reverse beeper.
