i have a 2000 volvo s80. My a/c panel lights just didnt turn on one morning and have been out ever since. As a result, the a/c won't work. I need some help figuring out how i can fix this without spending too much or anything at all if possible. Any help is greatly appreciated.

P.S. I live in texas and the heat is intense & i have leather seats...you can imagine how crappy it is! I have to drive to work in a separate change of clothes so i dont sweat all over my work clothes.
