OK, this is how mine works. If it?s on defrost the recirculate will only flash. Then go off , this aids in the defrosting of windows. If it?s on a/c and you turn the ac off the recirculate will turn off. If the heater is set at a high temperature (which is probably your case) the recirculate will flash only then turn off. The best way to make it work would be set the tempature lower on the thermostat until the recirculate stays on. BTW this is only true on 2008 models. The a/c system is completely different for 2003 ? 2007.
