The blower module could be bad, if the fan doesn't blow at various speeds selected by knob and if it works at all.

SOURCE: Lights for fan and ac knobs out. Power outlet doesn't work. Where is fuse box?

On drivers side under dash ( by your knee's) there is a black panel that you remove for access to fuses up under there. You also have one under the hood on drivers side marked Fuse/relay, or power distribution.

Ac fan doesn't blow hard enough 1985 300zx


If very little air comes from the vents, the fan on the blower motor may be damaged, or there may be a restriction in the vents, or a blend door may not be open completely.

unplug the heater motor and put a hot wire to it to check the motor if it blows if the wire gets real hot you need to change the heater blower motor. You will probably need to change the heater fan motor resistor. follow the heater fan wire and it will go to the resistor

Fan blowing while car is off


If the A/C knob is not set to 0 at the time ignition was off, the fan could run for a little and then off itself.
