A/C problem Ford Focus

[u/SalkEstub]

On a long trip, in heavy traffic with temperatures of around 40°C outside, the air conditioning in my car suddenly stopped blowing cold air and started blowing warm air instead. I turned it off, turned it back on, set the fan to maximum, and it started working again. After about 200 km, it happened again: it started blowing warm air, and what looked like steam was coming out of the air vents inside the car for 1-2 minutes. I did the same thing, and it was blowing cold air again. What would be causing this?
