My AC was blowing vapors. Next, my oil light came on and it smelled like something was burning, and I heard a beeping sound.
It sounds like you may have a severe oil leak that caused the oil burning smell. The oil light illuminates due to a loss of oil pressure in the engine. To avoid any further damage to the engine I suggest having a qualified technician to diagnose the source of the smell and address any issues that may have arisen.
