Air vents I was wondering if you can explain what would be the problem if no air is coming out of no vents except the floor!!!

I was having a similar problem with the vents not redirecting air when selected. I went onto the auto zone wed site and found very helpful schmeatic diagrams for electrical and vacume systems. That lead me to investigate a possible vacume leak. There was a vacume hose broken tucked away by the battery. I repaired the hose with thick wall heat tape and now the vents move normally. The vacume starts on the P/S top of engine runs by the battery into the fore wall. Once in the P/S foot well you will see a purple hose that you can quickly check the vacume pressure. It should be a noticable vacume. If not work your way back to the engine. If you do have a good vacume there then I would suggest going to a auto wreckers and picking up a new heater control module for around $90.00 in stead of the $240.00 fro the dealer. All you need is a phillips screw driver to replace it.
