i work at a shop and we just fixed a 1998 Buick regal with the same problem for some reason the wiring in the relay is backwards from what it is supposed to be and so to fix the problem we re-wired the high speed fan control from the pcm to the fusebox itself and now it works!it is the blue wire you have to replace! hope this helps! -TIffany
