On my 07 Ram sometimes when I shutdown and open the door, the radio stays on. Then times I can come out and the radio is on for no reason. Any ideas?

 

the ignition power supply is recieving battery plus+ current. check the ignition switch with a sutible test light. On the fuse panel check the radio fuse and see if it has current while the key is off...if so....more then likely the ignition switch or an aftermarket alarm system/remote start.

 

are the dome lights on to ?

 

Is it a timed feature? Maybe the truck isnt seeing the door open and thus leaving the radio on.
