Were is the location of the blower motor we have to replace it an cant find were it is

How do you know its bad if you dont know where it is to trouble shoot it?I would hate to see you replace it if it wasnt bad. What are your symptoms?The motor is under the cowl at the base of the windshield you have to remove the wiper arms then the cowl cover then there is another cover over the motor you have to replace the motor a certian way or you could damage the recirculation door.
