I had some blower fan problems once on my '78 Impala. On that car the wires going away from the relay went to a white plastic harness about 20"-25" away from the relay. I found that it had come slightly loose, plus when I unplugged it, found that it was filthy with built up dirt/oil/carbon, etc inside. Cleaning it up and plugging it back in solved the problem.
