I have an 06 Commander. This morning I noticed that there wasn't any heat coming from the vents. The blower was working and there was heat coming from somewhere (floor vents maybe?) but nothing from the vents and next to nothing from the front defrost, even with the blower and temp turned up to high. The vents did feel warm but there was definitely no force behind the warmth. Any thoughts before I call a garage? Thanks for any ideas!
