Thanks for the link I checked it out and it really only showed how he made the bypass and not which of the 3 heater core line running through the firewall, is there more than one heater core in my car?
Whether or not it is actually 2 separate cores I do not know (a look on realoem.com would show it), but the extra line is likely because of the dual zone controls. Unfortunately if she didn't say which hoses the bypass went on...
Have you checked for anything on e38.org or Timm's meeknet page?
