In the winter time my windows have trouble closing back up. It got stuck once and wouldn't come back up. My father decided to fix this himself, after he fixed the window problem my door now makes a weird noise (groaning noise) everytime I lock my car. I assume my father didn't do a great job and left something un-screwed when he took apart my door to fix my window. What is the best solution to this problem? If I happen to take it to a shop, how much is the estimated price?
I am assuming this is a "Power Door Lock Actuator Replacement" problem?
*a groaning noise from the door as the lock is operating.
