Jeep Repair: Jeep AC Problem, jeep grand cherokee, grand cherokee

Question
I have a 2002 Jeep Grand Cherokee Limited. Last year I got codes 51 and 53 and had the doors replaced. Now I'm getting codes 52 and 54. Appears to me to be the same problem in the same system. Am I right and what's with their design that keeps breaking every year or two?

Answer
Those codes have relevance for me. But I would imagine that they are for the actuators either being over/under voltage, out of range or any other number of faults possible for the HVAC system. As far as the doors breaking, what can I say other than they are mechanical parts and anything mechanical in nature can break. If it turns out that the same doors broke I would question the workmanship of the repair facility as they may not have not performed the repairs correctly.
