I am in the process of changing the AC evaporator coil on my 97 Wrangler. The Haynes manual is again usless, it only shows the earlier under dash AC unit. I have the dash loose and pulled back. I am now trying to figure out how to remove the heat/AC box under the dash. I beleive there maybe at least 4 bolts on the engine side of the fire wall. Also how do I disconnect the AC lines at the coil & dryer, I have removed the spring clips and the connections do not disconnect, is there a special tool required?

Thanks for the help
