Also make sure your evaporator drian is not clogged. When you turn the A/C on check under the passenger side you should see a black tube sticking out. Make sure water drips out of it with the A/C running. If it does not check the drian tube on the passenger side under the dash. You will see it going from the evaporator box to the floor. Also check it for holes or a tear.
