Heater Blower Fan Upgrade.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

After doing lots of research I replaced my non a/c heater blower motor in my 67 with a a/c heater blower motor. Supposedly, this is a common upgrade. But, when you do this, the fuse 10amp fuse has to be replaced with a 25amp fuse. My question is do I just pull out the 10 amp fuse in the fuse box and replace it with a 25amp in the same location and are there any other modifications needed? Just being cautious before I start frying wires. Thanks for the help.........Flat 67
