We are having the exact same problem on our 2018 G80. After about 1 hour of driving, cold air flow stops. The only way to get it back is to shut off the Climate control system for about 5 minutes then it comes back on full blast. Just spoke with the factory. They said they are aware of the problem but have no fix. Hoping someone on here finds a solution that we can take to the dealer and have them try. They do not want to drive the car for 1 hour to see if what they are doing has fixed it.. So far, nothing has worked after 2 years going back to the shop and the last time spent 1 week there.
