Need some info: Does the HVAC deck illuminate? Do you get a fan at all?
If you get no fan it may be the notorious fan connector. Open the glove box, ALL the way (have to empty it). Open it and remove the pull string. Then push the tab (on the right I think?) to let it fall down.
Then you will see a connector for the fan, if you lucky its not melted! Turn the system on and fan on hight, then wiggle it.
If it bad, disconnect with system off and try cleaning the contacts.
