Honda CR-V

Hello I’m new here and I have a question for you and that As already mentioned we have a Honda CR-V of about 3 years and about 112.000km. In the three years our Honda had never left us in the sting of the Lief even better like a Swiss clock. Nja at the kilomterstand have to show up quite different probl. what also falls in the drawer normal with us, but in case of problems where you can find no more infos in the net still in the manual as well as at the workshop then you can get even more restless just because we are a lot on the road and would like to do without surprises. Now for us dubious problem Some days ago when we were on the road came warm air into the car and that smelled so, so that you could not bear it inside. Actually only with warm air to drive. It does not point after spreading somehow after rotting hmmm One day later everything went normal …. but then on the third day this green light from the button ” Dual ” which never made it right/left 20 light can mean big degree ” What should be green at the second?
