1999 Evaporator Change

Anyone have any detailed instructions on changing the evaporator in a 1999 Intrepid? I have a Haynes manual but it doesn't cover it. I know that it is pretty labor intensive and involves removing the dash among other things. Also, anyone know if you can replace or work on the rack in pinion from underneath the vehicle?

I have some bad news,the whole dash has to come out and what is says in the Alldata on the computer
