Hello dear US car, respectively Cadillac fans, for almost 4 years I drive a Cadillac CTS 3.6 limousine from year 10/2008. Regarding driving comfort, performance and rarity value I love to drive with this vehicle, or to cruise. The Cadillac is currently equipped with a season mark and stands in my garage in winter. I am very happy to be able to move it again almost daily from April… However, there is a problem since last summer. 4 weeks before the season back to end e was, I wanted to go with the Cadillac a bigger tour, put the air conditioning and ventilation on high level and – nothing came… The ventilation hums, however, no ventilation, not even a lukewarm, out of the openings (the climate is no longer cooling). I tried everything, put the ventilation on a small level, set it on a large level, air conditioning and air conditioning out, but nothing went on. I assumed that logically anything about the ventilation, maybe even the complete unit defective Does anyone have any advice about what can be broken here (possibly a known problem with the CTS), what spare parts cost and where to get them cheaply, but above all also how to remove the center console and get to the ventilation unit?? I don’t see any screws, clips or anything else. Maybe I have to go somewhere else?? I am grateful to you for every tip, for every idea! Maybe someone has already had the same problem here and can explain his approach. maybe someone also found something on an American side that could help me… Thank you very much and thank you very much, Markus
