No wonder.
Your (1999-2000 MY) A/C control module is incompatible to ECUs 2001+MY with 1024kb witch using another version of A/C and fan control.

Indeed some of the widebands use different ac module wiring including CAN specially on the transverse platform. Also I told you before, you cannot go switching from narrow to wideband and vice versa withiout hardware commitment,stuff wont work.
