This very common symptom is typical of a failed blower motor resistor. Easy fix and about $40. It is up in the blower duct behind the glove box and is accessed from below. Remove the lower kick panel and drop the glove box forward and out of the way so you can see the electrical connection to the blower motor.

2002 Chevy silverado fan blower only runs on speeds 3 4 and 5 where is the relay located?
Its not the relay, it is the blower motor resistor.
Why does the Fan motor for Chrysler Sebring not work in lows speeds only 4?
The common cause is a failed blower resistor.
Heater only working on number 4?
It sounds like the blower resistor assembly is defective. All fan speeds except for high go through resistors (that is what controls the speeds from low to high). Number 4 is high and has the full 12 volts going to the fan.
Why would a 1998 Honda Civic AC blower only work on settings 3 and 4?
I've had a similar problem on my 98 civic ex. There's two resistors wired to the fan control. One for speeds 1 and 2 and another for speeds 3 and 4. I suspect the one controling the 1 and 2 speeds has blown.
What would be the cause of your heat only working sometimes in your Hyundai Elantra when you can hear the switch clicking when you turn it?
Possibly a fan resistor. Does it work on only certain speeds like 1 and 2 but not 3 and 4?
2004 envoy heater fan only works on 4 and 5 won't work on 1 2or3 how come?
Check the blower motor resistor as it controls the fan speeds. Also check the blower motor as it will burn out resistors if its drawing to much amperage

What could cause the heat switch to only operate in the 5 setting?
Most heater blaower motors have 2 relays: 1 for speeds 1-4 and a high speed fan relay for 5th speed I do not know what kind of vehicle or location of relays Most heater blaower motors have 2 relays: 1 for speeds 1-4 and a high speed fan relay for 5th speed I do not know what kind of vehicle or location of relays
Why do speed 1 and2 fan speeds do not work and 3 and 4 do on my 95 ford windstar?
Blower Motor Resistor Pack is defective.
Why doesn't fan blower speed 1 2 3 work and speeds 4 and 5 do?
the blower motor resistor is broken, get a replacement.
What is the problem your fan and ac only works on speed 4?
Your fan motor is going out.
Why does my Rover 25 fan heater only works on 3 and 4 but does not work on the lower speeds?
The stage 1 relay has blown! it is located behind the glovebox door above the heater blower. # find it # pull it out # replace it job done:-)
