Opel Astra H - horn doesn't work - how to repair the CIM module

I've heard that users of Zafira and Vectra (production years around 2005) also suffer from this manufacturing defect. I think the tutorial is more suitable for electronics engineers/hobbyists. Anyhow, if you know how to *reliably* solder two wires together then I'm sure you succeed with the repair:) The video shows how to: 1. remove airbag 2. remove steering wheel 3. remove CIM module 4. CIM disassembly The links that helped me the most: 1. 2. 3. 4. PL: Opel Astra H - klakson nie działa - jak naprawić moduł CIM
