You have no air movement at all or it just isn't blowing hot air, only cold?

Have you checked the blower fuse in the underhood fuse box, it is #35. Also check fuse #44 in the rear fuse box.

If the fan is running and there is no air movement at all, I would check for blockage at the cabin air inlet hose coming from the air cleaner.
