My a/c blows only hot air on 2003 Kia Sorento

This started right after my credit card got stuck behind the drawer under the A/C controls.... Please help !!! Thanks

Credit card must have been expired. Try a new one to see if the A/C will accept it!

You will have to have a mechanic LOOK at this, no way to tell what may be wrong.
