If mine is replaced, and then my warranty expires, will they keep fixin it after that?

I'm getting nervous

 

i had this problem a couple weeks after i got the car, i had just taken the door apart to put in my speakers and it started doing it, ..it would drop only about 2 inches whenever i put the top up or down. it did it for a week, then i took the door apart again to adjust something on my speaker and after reconnecting everything it didnt do it again, . that was about 6000 miles ago.

 

I just ignored mine over the 2 years i have owned it and it now works fine. Don't know what happened.
