    Default A/C stopped blowing cold air

    So my mom borrowed my truck yesterday and said that the A/C wasn't blowing cold air. I got in it yesterday night and it seemed to be working fine. So today she borrowed it again and it wasn't blowing cold air. I thought she didn't know how to use it. So I got in the truck and she was right. I turned the A/C all the way up and I had the temp on 60 degrees but it was still only blowing hot air. But when you switch fan speeds or something like that it will blow cold air for a few seconds and then back to hot air. Any ideas?

    Low freon, or clogged orifice tube. What's the service history on the ac?

    Ok thanks. Umm no idea about the service record. I bought the truck last october from a GM dealer and we have never had any problems with it.
