ISC/IAC Data and Repair Links

Here is a good page about the ISC along with some links of places that will repair it for you. They only charge $90. If that is in your budget I think it is worth having it function properly.

As far as removing the IAC; I do not think they meant to remove it, you should just unplug it and then adjust it manually as noted in a previous post.
