02 ram radio doesn't work pwr locks stop working..
 

my radio stop working and my key fob stop working also and a red light stays on after I turn truck off and remove key. i've changed fuses out but it hasn't helped. any ideas???

Welcome to the site. How old is the battery? Does it start up and run fine?

not sure on age of battery. but truck does start and run fine.

Well then it has to be in decent health.

My initial thought is the security system some trucks came with but I'm not sure 02s came with them. Can anyone help out here
