Welcome to Just Answer,
The blower resistor card is a common fault with your cars's A/C system, Remove the resistor and check for burnt spots on the circuit board.
The blower motor resistor is located in the lower right hand corner of the HVAC module. This resistor is located between the blower motor and the front of the dash.
