if it,s the blower your talking about....................yes...it could be the motor/relay...........could also be the blower switch itself......try testing for power at the motor........if you have power there.....replace the motor.......if not....check the relay or the blower switch.

remove the connector from the blower motor and put a test light across the two wire terminals.[should be black and purple wires]turn the key on and put the blower switch through all speeds and watch the test light. if the light comes on, you need a new blower motor. if not, check using your test light, for power [voltage] at the resistor connector orange wire. if that is okay, you need to remove HVAC module and test for voltage, ground, and open circuits to resistor. hope this helps.

at 6 years old, I'd guess the blower motor.
