Possible Blower motor problem

jeepers94

93 Integra GS
So whenever i turn on my heat there is a lot of noise and the higher the setting to louder the noise. I'm thinking its the blower motor. Does anyone know of a good guide to use on this. Its a 93 integra. I was gonna just go from under the glove box but the 3rd screw is against the fender. thanks.
