Wiper Question?

[OldSkool71]

My wipers were not working at all when I got the truck. The switch was real sticky like it had not been used in some time. I got it freed up but then nothing out of the motor(no movement). It did however make a slight noise like it was trying to work when I would turn the switch on/off. After screwing around with it for awhile and hoping it would work, it has started to work now. My question is the wiper motor kinda loud? I have never heard it before but it seems kinda noisy to me. Any imput would be appreciated. Don't get me wrong not complaining just wondering if I may still need to replace it or something. Im just glad to have some wipers now that the rain is on the way. Also I am stoked that our site is back up too....
