Use a multi meter to trace the power.

With air conditioning your Catalina has a 30 AMP fuse in line at the alternator for high speed only on the blower motor. Check that. You'll also want to pull the climate control panel. There is a switch on the back of the control panel that sends power to the fan switch, then to the resistor block, then to the blower motor. You probably have a blower motor relay mounted on the firewall near the air conditioning evaporator box on the passenger's side as well. Is this a manual system or automatic climate control? Hope that helps! Jim
