Pull the dash trip off gently from bottom to top, (just the dash
trim by the climate control) and there will be 4 screws on the
climate control module. Its best to buy a used 1996-1999 Mark VIII
Climate Control module, since they have "Hard Buttons" on the
climate controls. Pull out the old one, and replace with the new
model. Newer model climate control modules are totally compatible
w/the 1993-1996 models.
