First post and I Need help. My driver side mirror in my 91 rs will not stay in position. The housing is good to go but the actual mirror can be adjusted with the manual control **** from the car a little bit but I have to push it into place and within 45 seconds it falls back down. is there way to tighten it up or do I need to buy a new cable assembly. Of so does anyone know of where I can purchase one. Ive searched and searched but I cant find anything. Thanks and looking forward to reading and posting in the forums.
