    When I turn the AC on manual or auto it blows out the defrost. It doesn't always do it, but quite a bit in the last week.

    Have you brought this to the attention of you local dealer? I can also look into this for you with your VIN. Please feel free to contact me via private message. Thank you in advance.

    Tricia, GM Customer Service.

    This is on your 2005 GMC? How many miles are on it, how long has it been happening?

    It just turned over to 90,000 last weekend. It did this once about a month ago, lasted for a day and didn't do it again until this weekend.
