Has anyone had problems with there being no heat or air blowing out of the floor vents? I don't know where to begin to look to fix this problem. Any suggestions?

 

1;fuse box
2;blower motor
3;the switch

 

One easy thing to check is to make sure the carpet is not covering the vents.

 

Should still be under warranty, take it to the dealer. The controller came lose on my friends truck. Also check for a critter nest. even though it is a newer truck you would be surprised at how fast a mouse can build a nest.
