The first thing that you should check is the wiring going to the blower fan for the front evaporator. If that's not the case you should unplug the fan turn your key on turn the fan on high then check to see if you got 12.6 volts at the connector. If you do replace your blower fan. If not it is possibly a power control module for the blower fan. You should have a technician verify that before you buy that because it is a coslty item.
Hope this helps.
