I would not advise you to take such a risk because there may be sad consequences, both for you and the car. It is best to fix the air conditioner and not do anything extra. Moreover, every vehicle should have air conditioning. Otherwise, it is impossible to stay in the car in the summer, isn't it? Maybe I think so because I was in Texas last summer, and it's impossible to live there without air conditioning, to tell the truth. It's good that I regularly clean my air conditioner in this service socool.sg; otherwise, as my friend, I would then pay for a new radiator.
