Hello, my vehicle is 2011 model 5008 at 80 thousand km, about 1 hour after starting the air conditioner, the gearbox malfunctions. When you turn it off and on, it continues to work, but without turning on the air conditioner. We put it in the machine, it did not show any malfunction. There is no other problem in the vehicle, everything is complete, has there been a problem with the air conditioner in this way? I am open to suggestions
