First make sure the compressor is running when you have the A/C turned on. If it is not, then have the system serviced to bring it to full proper charge, and have them add the UV dye to the system while they are charging it.
Get a UV pen and glasses so you can see the stuff glow, and run the A/C full blast for a week. Check for leaks.
You can check the dampers for movement if you believe their is a war raging in your dash. Just move the controls from hot to cold and listen for movement (blower on low). It may help to have your head under the dash on the passenger side while doing this to hear things better. If no movement is heard, then a little exploratory surgery could be in order.
