How can I fix the air conditioning in my Audi 80 if it is blowing hot air?

My Audi 80's air conditioning has suddenly started blowing hot air instead of cool air. What could be the potential cause and what steps can I take to resolve this issue?

It is likely that there is an issue with your air conditioning compressor. This can be caused by a leak in the system or a malfunction within the compressor itself. I recommend taking your car to a trusted mechanic to have it checked and repaired.

Another common cause of hot air blowing from your air conditioning could be a blockage in the air vents. Check to make sure there is no debris blocking the vents and if so, clean it out. If the problem persists, it may be necessary to inspect and possibly replace the ventilation system.

Sometimes, a faulty air conditioning control unit can also cause hot air to blow. Consider replacing the control unit or getting it checked by a professional if necessary.
