Does anybody know how to disable this super-annoying chime on our '05 work truck? I didn't find much luck in the search forum... .
I think you buckle up, turn the key to on position. Then within 10 seconds, unbuckle and rebuckle 3 times. On the third rebuckle you should hear a chime indicating a change or if not, turn off key, then back on. When you unbuckle, it should no longer chime.
I cut the two wires under the seat and sodered them together... works great...
