Can anybody give me any pointers? I have a 3.0ltr Td V6 2003 (53 plate) Signum. The Internal blowers are stuck on full, and don't turn off even with the ignition off. I think its down to 1 of three possibilities. 1, the blower resister.
2, A relay ( if there is one ) or 3. the console itself.
The last one ( no 3 ) is most unlikely because the heating is still adjustable.
Any one with ideas or past experience would be most helpful
