It's been a while since I did this, so please use your craftiness to determine if you need to change the order at all, or if I miss a step.
You can replace the clock without having to replace the climate control. I know that for sure. The entire dash console comes out in one piece, and each of the components attach to the back of it.
You will need to remove the black or wood grain trim on the console, which can be loosened and pulled up and off by prying with a small slot screwdriver near the corners. The rounded piece between the ashtray and climate control pops out also. Look for pry spots on the top edge of it. Then remove the 4 bolts that hold the dashgoard console in. You may have to pull out a cover piece first, by grasping the strip between the air ducts and the clock.
