a/c is blowing warm and my engine is overheating

my 2002 Hyundai Elantra a/c is blowing warm and my engine is overheating. The belts are all in place. there are no leaks of coolant on the ground. There are no noises coming from the water pump. Do you have any ideas what may be the problem? I ran over a deer a few weeks back on the interstate. The car has ran fine since, but I did sustain some damage around the radiator (braces got bent up). I am wondering if this problem has popped up after the fact. Answer: Most likely cause (since you hit a deer) would be that there is a hole in the A/C Condenser (Reference Diagram) that is located in front of the radiator. This would allow the freon to escape. As for the overheating, since some brackets were bent, etc. there is probably some damage that was done to the fan assembly not allowing the fan to function for the radiator. This would make it overheat. Another thing that would cause both issues would be air flow restriction. If there is deer fur stuck in the condenser and blocking air flow, neither the A/C system would work properly nor would it allow air to flow through the radiator also causing the engine to overheat.
