BMW Questions? Ask a BMW Repair Expert for Answers.
Hello, I'm Brandon - BMW tech.
Can you tell me if the AC compressor is kicking in?
You have to call or email the customer service.
Do you still want me to help you? or would you like me to opt out?
Most likely the ac compressor or the ac relay failed.
Unless there is leak in the ac system. All these items require a trained tech to visual inspect it.
Let me know if you want me to continue.
