there is a seperate relay for the high speed in gm cars its called the high blower relay switch there's also a high blower resistor its usually located inside the evaporator/blower housing if you take out the bolts it looks like a spring coil the're the things to check.good luck!!

ok i reread your post you ckecked the resistor so your problem is the relay it is usually the three prong plug on the blower housing, im not sure if its in the same place on all gm cars let me know if this makes sense.
