BMW i3 & i3s (Non-REx) Air Conditioning Pressure Switch – 4-Pin
This air conditioning pressure switch monitors the refrigerant pressure in the BMW i3 climate system. The car uses its signal to run the compressor and cooling fan safely, and to protect the system if the pressure goes too high or too low.
A faulty pressure switch can stop the air conditioning blowing cold, make the cooling fan run all the time or not at all, or store a refrigerant pressure fault. On an electric car the same circuit also helps manage battery and cabin cooling, so it is worth fixing promptly.
