Remove the fuse panel nuts (2)
I think there was a screw also.

There is a grey box about 1"x3"x4" connected to the back of the fuse panel. At the bottom of this grey box is a plug with about 8 or so wires in it. Unplug this cable.

After disconnecting the grey box (ICU), there is a clip on the short sides that holds it on. Unclip this grey box. On the ICU, there is 2 clips on each of the long sides. Use a flat screwdriver to push these clips.. Try not to break them or you will have to use some black tape to hold it together later.

Once you have the ICU open, you will see there is a circuit board, and on the top right corner is a piezo tweeter. Pull the circuit board from the housing and remove the piezo tweeter using a soldering iron. (it is the round black plastic thing about 1cm in diameter by 1cm tall, with a hole in the top) If you just want the beeper to be quieter, I suggest a little piece of tape over the hole. I chose to remove it alltogether.

Put the whole thing back together and plug the ICU back into the fuse panel and reconnect the wire to the ICU.

Now your hazards and wipers should still work, however you will not have that annoying beeper any longer.
This fix took about 25 minutes but I had to figure out how it all came apart.
