97' V6 Passenger Window?

[mstg97]

Ok so i have been living with with my passenger side window not being able to go down for a while now. Now that its summer im wanting to fix it. When i hit the button to make the window go down sometimes it will and sometimes it wont. Meaning that if it goes down it might not come up so i never take the risk. Also my door locks when i hit the switch they make a grinding sound and u have to hit them rapidly maybe 10 times to get both doors to lock so i have just been manuely locking them.

My question is does this sound like a fuse problem? Is my window regulator motor bad? Could there be bad lines running to locks and window buttons?

I took the inner door panel out just to look and i really dont see anything oviously wrong but then again i havnt tried to fix this before.

Any help would be great
