My friend got out of my car the other day and i heard a rattling by the door...so i get to work and go to roll up my passanger window and the ****er just breaks...so i get off and take my door apart...a bearing on a slider broke off..so what do i do now?? How can i get this fixed. Im gunna go to the junk yard and see if they got an assembly. Has anyone else had this problem??
