I was driving down the freeway when all of a sudden
without warning my AC stopped working. The back AC is
fine. I cant hear anything from the AC and I don't feel
anything. What could be wrong?

Hi the rear AC unit is blowing cold air fine and the front is warm is usually the sign of a bad front H/valve usually stuck in the open position this valve moves to the ambient air temp and if sticks will not be the correct orifice size to change the refrigerant from a liquid back to a gas ....both the front and rear AC work off the same compressor and share the same pluming so its safe to say that you don't have a leak or low refrigerant due to the rear unit is so far back ...and they both use an H/valve in front of the evaporator core.... so logically we can says that it is a bad H/valve...hope this helps
