Tim, so high speed does not work and the other speeds do? If so, the high speed relay could be bad, OR the wiring itself. In the picture above, that mulispliced wire on my air cleaner had been "fixed" several times due to excessive current through weakened wire. Check for opens near the fuse holder or at the connection terminals. Turn on blower and wiggle the wires. If it starts comning on, look for wire smoking, or feel for hot areas or even watch for sparks. That blower pulls 20-25 amps on high!
