Isuzu Repair: 1996 Isuzu Hombre, isuzu hombre, dash vents

Question
I have just replaced the whole a/c system on my truck. The air blows cold but no matter what setting I try to put it on, the air only blows through the defrost and the floor. Is this an electrical problem or is there some sort of baffle that I can turn to make it blow through the dash vents? If so where is it located?

Answer
Well sounds more like the baffling or vents could be stuck closed for a few reasons Johnathon. Such as the linkage is broken or seized. Or the vent mechanism itself is faulty. All of the components located are behind and underneath the dashboard and the SRS air bags will need to be deactivated to be able to work in this area safely.
