I have recently replaced the blower motor resister because the fan would only work on high. Now the blower speeds seem to be OK, except for the highest speed which is supposed to be invoked when the recirculate button is pressed. Can anyone tell me what invokes this hyperwarp blower speed?

fwiw, i do not have knowledge specific to your vehicle, but usually the hyperwarp/louder blower sound in "recirc" mode is not from the fan going faster. the louder sound is due to the recirc itself. if the noise/air does not change when you switch from normal to recirc, it means that the flap/door that controls the recirc is not operating, possibly due to a vacuum leak.
