Hello dear forum members, I need some help with my Lancia zeta TD 1.) I have problems with the blower motor. The whistle and squeak at low blower level, and always driving with full blower level, is annoying in the long term. Where is this installed, and how can I get this? 2.) Where is the relay for the air conditioning (I think in the motor-side fuse box) located? This does not work for me, but can remind me that when I turn on the Anla This is no longer the case. 3.) The ventilation is not getting really warm, although the engine has operating temperature. Can it be that the heat exchanger is clogged or, or does anyone else have an idea? In advance, thank you for your help and at least for reading the text.
