Some blowers high speed is controlled by a relay in the maxifuse relay center. If the relay were stuck I suppose it could do this.

Not sure which relay. Search around, maybe someone has identified it before.

Does this SE have the Electronic Climate Control, with the Steering wheel controls?

I'll bet that the Blower Control Module had died and the Blower is stuck on high..

The Blower Control Module is on the passenger side of the Blower Box, Under the MAXIFUSE/RELAY center.... Follow the wires from the blower, should take you right to the Module

Default relay

Take your floor kickpanel off below the glove box and there should be a sticker with relay and fuse identification.
