My 2004 does not put out the heat to the floor like most cars do. It is a little weak at the defrost to, but the vents blow strong and it is hot. Just doesn't seam to switch to the floor like it should. Does anyone else have this problem, or can you tell me what may be up with it?

 

Auto climate controls, if so are there any codes. In the DIY section there is a post about getting those. Has the cabin air filter been changed lately. There is the "mode motor" that controls this, might have to check the movement of it.
