The blower motor resistor card is located under the glove box. You have to take the bottom panel from underneath the glove box out(be careful not to break the wire clip that holds the wires in place on that panel). Once you take the panel loose look in the back. You will see the blower motor. Behind the blower motor is the card. You will need a 9/32 for the panel and a 7/32 for the card. It is only 4 screws total to remove and 2 wire harness clips. It is about a 15 minute job.!!

Try dropping the glove box door to get access. You should at least be able to see it at that point. The resistor is just two bolts and a electrical connector after that. The hard part is getting to it.
