well i changed my leaking heater core and everything seems ok. no leaks, and everything works as before.the only thing i have left to do is charge the a/c. thanks to everyone on this site for their posts, it made the job less painful!before i completely re-installed the dash, i hooked the battery cables up to check all of the electric components. the door/key/headlight/seatbelt warning chime seemed to be coming from the general area of the glove box or the passenger airbag. i didn't spend more than a couple of minutes looking because it was getting late and i had to get the truck back together.my question is, does anyone know where this annoying thing is and how can i disable it?!thanks again for all of your help.

I wouldn't do it. You'll never know when you might leave your interior light or headlights on....and kill the battery. But thats just me....

 

The door chime is on the bottom of the steering column. Just snip and your done.

 

just take the seatbelt connector apart under the drivers seat it will ding for lights but not keys door or belt, besides o2 the lights kill after 5 min ne way..
