I have a 2006 Honda accord coupe. My AC/Heater only blows when i'm going over 60 MPH. i took it to o'reily's yesterday and despite not being able to connect the car to the reader to diagnose the problem..the guy could tell just from looking under the hood what the issue might be. My fans are working, Pulley (although really loud) is working and they Freon line was cold. Should i replace the motor and resistor to be safe?..also in regards to the loudness in my engine cause (Pulley the guy says"..would replacing that as well quiet my car?
