Possible reasons the low speed blower settings don't work:
The switch or the wiring has failed.
The resistor has failed.
A connector is loose or has failed.

Why does blower fan work on all speeds except high speed on your 84 Chev El Camino and you checked contacts on switch?
Sometimes it's because the high speed fan operation works in conjunction with max air. Try turning the air on and see if the fan kicks in high. Just a thot.
How do you change the fan switch on 1999 Mercury Cougar?
Why are you replacing the switch? If the fan works only on high speed, replace the fan resistor. There was a TSB for this.

Avalon Ac works only on high?
Be more specific, if the fan speed only works on high then it is most cases a bad resistor board for the fan, a $10-20 part, available from an advance, murrays, or lee or similar auto parts store.

If you mean the fan works on high only it's the blower motor resistor.
