93 400 SEL Heater Blowing Cold

Any thoughts as to what may be causing my heater to blow ice cold air? It started out just on the drivers side, now there is no hot air to be found. Any help would be great. I guess there is some diag test I can do, but have no idea how to do that. Colorado mornings are cold!
