A/C / HEATER FAN

Ford F-150

I have a 2000 Ford -f-150 w/ triton v-8, 79k miles
My problem is that the fan only blows on high speed
I replaced the switch in the dash but it didn't help. Are there relays or something else I need to replace?
thanks

Could be the fan relays or resistors, usually located somewhere around the heater box. Or the switch itself has failed, in my experience, high speed only was a sign that the resitor pack had malfunctioned.
