1999 c5 defroster question
When I hit the front defrost button, should the AC button light up and turn on? I'm thinking not but is there something to look at to get it to operate correctly? Thanks!

Yes, the AC light should turn on with the defrost button. The AC compressor removes moisture from the air. Since condensation is excess moisture, having the AC on helps. Even when it is cold, the compressor still helps remove moisture even though the air is blowing warm.
