Hello iam hoping someone can help,I have a 2003 audi a4 and my partners. Came in from work there and passenger windows stuck right down,when I tried to put it up it went very slowly about a inch then made a grinding then a clunk noise then stopped, now motor does go up and down noises but window won't move,I manage with door open to use both hands and slide the window too close it,iam thinking it sounded as if it stiffened up then broke maybe a cable or runner or something,iam going to book into garage but was wondering if anyone knows wot it could be and rough cost to get fixed,thanks for any help
