problems with radio and door chime
hi i got a 03 gmc 1500 it has a aftermarket kenwood in it and i did not install it but the other day i decided to put a aux cord to it and had to pull it out. before everything worked fine and no problems now it only plays with the ignition on and not running with i giggle the shifter but only plays for a few secs and the door chime as well. the door chime does only works when the radio wants to. if i turn the key once forword it will work all the time and play and chime. but it will not work when running. i have checked fuses and everything is ok i dont know what i did and called two shops and they have no idea either. iam thinking either a bad ignition or short somewhere. if theres any advice please let me know. you can emial me at firstname.lastname@example.org thanks !!

Make sure every thing is connected...the door chimes on the NNbS trucks works via the radio/Onstar....any time you install an aftermarket deck you need an adapter to retain the door chimes etc..

i have the 06 silverado and if you dont have onstar you dont need the adapter, you just loose the door chime, for me i was happy not to have that.4.8L Vortec | 6inch Lift | 35'' BFG ALL TERRAINS | K&N Intake | AirRaid Throttle Body Space | 3inch straight pipe dumped at rear axle | BlackBear Tuned | 2 13in JL Audio Subs | 1000watt HD amp, 2.9 cap | Kenwood Dble Din | Gibson Hi Flo Cats | HIDs Hi/Los 55watt 8000k |4.56 gears |

You always need the pac adapter from 2003 to 2011 always, if you don't use it the BCM can turn on the thef systen and lock the ignitions system in the worse case,
you first will lose the warnings, lights on, door open, key on the ignition, low fuel, air bag warnings, couple of months later the airbags stop working and vehicle gets hard to start in the mornings

To the initial poster. You probably have a GMCO in your truck. Do I have onstar and Bose? The GMCO was one of the first solutions for interfacing with the CAN system (notice I didn't say CAN-BUS system which is the revised version of the CAN system, the CAN system came out in 03 and the CAN-BUS system was released in 04, the GMCO harness interface doesn't work very well with the CAN-BUS system.). Back to the point. The GMCO modules have a notorious failure rate that cause symptoms like you are describing.
