Hello and welcome!
My name is ***** ***** I can assist you with your question.
The first thing to do is check the AC charge or freon level just to be sure it is full. If it is low it may not cool properly.
If that checks out good, I would suspect a restricted expansion valve or a an issue with the rear air mix door motor/flap. You can check this with a scanner if you have access to one or you can physically feel the tempature of the rear AC lines. Check the 'feel' of the lines from the front to the rear evaporator. Look for warm to hot on the high side. If a 'cold' spot is located, check for a restriction. Check the low side return line. If warm, check for a restricted expansion valve.
