help

my blower motor is only blowing on high, the lower three settings hardly have any air coming out of the vents. I played around with the switch and the hvac switch, just to see whether it was the switches. Can you tell me what the problem might be.
Thanks in advance for any assistance.
Andrew.

Make, model, and year would be very useful. My crystal ball is in the shop at the moment.

It is most likely the blower resistor. It can be found mounted to the heater/AC box.

The box is located on the passenger side behind the instrument panel.
Look for a 5-6 wire connector on the box either above the passenger footwell or behind the glovebox. The resistor will be held in with 2 screws.To see above the footwell, you may have to remove a trim panel from the IP to the firewall.
