70 442 High Speed fan With AC
Fan runs on first three speeds but stops on high. What do I need to do?

Check the fuse in the little holder that comes off the horn relay junction post. Also look for burned connections.
Can you hear the relay by the brake booster click when you switch to high?

There is an inline fuse in the firewall, in the are behind the distributor. Change that fuse and your problem should be gone.

The blower resistor on the A/C box under the hood is corroded.
