Sounds like the typical high speed blower relay went bad. Happens a lot on this type of AC system.

There's an inline fuse, near the alternator, for the high speed only setting of the blower motor. Check that fuse to see if it's blown. If it is, replace it. The fuse will be a 30 AMP. If it blows again check the blower motor. If it's dying it can draw excessive current on high speed. Hope that helps! Jim
