2008 Silverado- door switch problem

[jasonmd13]

My 2008 Chevy Silverado does not horn chime to when I use the door lock on the key fob, it does Not say door is open when I put it in gear with the driver's door open, remote start not working and the dome light will not turn off. Does this sounds  like a faulty door switch? Only weird part is most faulty switches says door is ajar, where mine does not say it's open when it is open. Thanks for your help.
