How do i replace heater blend doors on 1996 jeep grand cherokee

I haven't done one on a 96 before, but have on a 2000, while they are different body styles i assume they are very similar. On the 2000 it required removing the entire dashboard, center console and steering column. Evacuating the A/C system and draining the coolant. And finally removing and disassembling the HVAC box. While your in there take a good look at the heater core and Evaporator as they are somewhat common leak points in their corresponding systems. Won't want to put it all back together to find out a few months down the road that the evaporator is leaking.
