Under the hood, look on the top/engine side of the evaporator housing. The evaporator housing is the black housing on the passengerside bolted to the firewall where the pipes for the AC go into.
Remove the small bolts and pull the blower motor resistor assembly out. Verify the condition of the resistors. If you have an ohm meter make sure none of them are open.
If that checks out, replace the Relay mounted on the firewall on the engine side of the blower motor housing.
