I don't know of any short of clipping either the door jam switches or the key-inserted switch. There might be a tech2 option a dealer can program in.

Although I have thought about just shooting the piezo full of rtv...

 

DON'T CLIP ANY WIRES YET. There is a way, I did it on my '01. Let me find it.

 

This would be great. I'm not willing to loose the dome lights and such - which is why I've never done something about it.

 

answer, i believe you hold down one of the preset button, i think its 6, but either when the truck is off or on, radio on or off, something like that. and it will ask low, high, or off? its been so long, i dont remember.

 

only way i know of to kill the chime in 03+ trucks is to swap the stereo out and not us the adapter. i tried to adjust the lvl using the #6 preset button but it only goes loud or normal.

 

I hope Neil remembers how he did it. Right now if I want the radio on and left door open, I just engage the door latch with my hand to make the chiming stop. But sometimes when I go to close the door, I forget to unlatch it and BAM the door pops back open

 

happens to me every time

 

Sorry to leave you guys hanging, been busy.

Here's how to do it on 03+ year models.

I'm still searching for how I did it on my '01, but haven't found the instructions yet and I don't have my truck anymore to see which wire to disconnect. For the 99-02's it's just like the 03+ way except I think you have to pull the middle wire harness to the BCM and disconnect or clip a gray wire. I'm not 100% sure on that though, but if someone wants to try it they can. I'll keep looking for the instructions in the meantime.

 

Still interested in the 99 GMC.
