Moving the AC controls on a 98 grand may not be as easy as you think. You have to trace, re-route, and extend about 10 vacuum lines that go to the control; It isn't electronic.
Not saying it isn't impossible by any means. Knowing what you're getting into is much better than not
I did it on my cherokee, it wasnt that difficult and I didnt have to cut anything to get it to move. The controls are pretty similar in form and function, I just moved it up higher and allowed for a 8" touchscreen //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
