I am saying that I tested mine and it was drawing 12 amps on high. I know it's a 30 amp heater CB that is tripping. Since my blower motor isn't pulling that much amps it must be a combined amp overage. Seems logical that anything downstream from the 10A a/c fuse that was pulling too much would blow the 10a fuse. So we can rule that out. Could be the blower motor, heater relay, bad grounds, worn blower resistor, and or worn switch. If you have something positive to contribute that would be great. here's a schematic of the a/c wiring if anyone would like to add to the conversation. "C" at the top of the image is the power coming in from fusable link. the W-B white/black wires at the bottom are ground wires going to ground.
