Any attempt at shutting the indicator lights off proved futile although eventually the rear defroster light turned off on its own accord.

Minutes later, what appeared to be vapor and would soon transform into foam began seeping/spitting out of the air grills above the thermostat panel. This eventually stopped five to ten minutes afterward.

Upon arriving at my final destination, I opened the hood and heard a sort of high pitched metallic buzzing and saw a spinning belt wheel from what I believe to be the A/C compressor.

My question is whether or not anyone is familiar with this type of issue and what can be done about it. Any help or advice would be immensely appreciated!
Your evaporator has a hole in it. The oil and refrigerant came out. The lack of oil did not make the compressor happy. At a minimum you'll need a new evaporator and receiver/drier and a set of O rings around the system. It will need to be flushed clean. There is no way to know for sure if the compressor is gone until it's taken off the car and flushed (if any pieces of black chunky stuff or metal comes out it's not good.)
