ouch!! The FSM (manuyal) wiull say that you can remove the necessary parts through the dash by removing the console. In reality, that is not possible. By far the easiest thing to do is to remove the dash. It is only 13 screws, 2 big bolts, and a lot of extrasneous stuff. Once you do that, everything will be open for you work work on easily.
Not to mislead you. this is at least a weekdn of work to replace a part worj $100.
