When I turn the fan on you can hear it running but the air flow seams to be comming out of all the openings. You never get that blast to the windshild, dash vents, or floor. Maybe a little more comes out when you adjust to 1 of those settings. It heats or cools fine, it just takes a while. as it seems like the air comes out all the opens. Where should I start? I've always wondered if something fell down the defrost opening and is blocking something, although Ican't heat any vaccum noise when changing between the openings.

hello and thanks for donating If the ventilation controls are not working properly then it could be bad wiring or faulty HVAC control module. Best thing to do is narrow it down, to do so just follow steps below.. let me know if you need further assistance with this issue.
