AZC Fault Codes...need parts! HELP almost winter!

I have a 1999 Jeep Grand Cherokee Limited. It has the dual climate control system but recently my AC and Heat have stopped working all together. When I turn it on, nothing happens, just a pounding sound from behind the dash. I recently did the AZC self diagnostic test to get the fault codes for what is wrong. I came up with 45, 46, 47, 48, 54, and 56.

45: Mode motor not responding
46: AI (recirc.) motor not responding
47: Left temperature door not responding
48: Right temperature door not responding
54: Left temperature door travel too large
56: Right temperature door travel too large

What I am wondering is what are the parts I need to replace to get this fixed. I understand that the whole dash has to come off and I have found someone to do that but I am not sure on the parts I need to order and replace.

If anyone could help me out it would be greatly appreciated.
