Cadillac CTS 2004 Broken AC Knob

Freddy’s Question: The AC knob on my 2004 Cadillac CTS has broken off. I tried super gluing it back on, but it won’t hold very long before it breaks off again. Am I going to have to buy the whole expensive control unit?

Answer: No, you won’t have to buy that VERY expensive entire control unit just because the knob has broken. So many of those knobs have broken that the Caddie dealers now sell just the knobs themselves. SO, you might just mosey over to a dealer and buy a couple. Keep one as a spare in the glove box.
