    I am constantly burning up my A/C-heater fuse to which the blower motor is dead. I do not know what is causing this although I have checked the blower motor relay and resistor assembly.

    When checking the fuse after inserting a fresh one, the fuse is hot on one side to which I have went through 20+ 20 amp fuses and most recently, 25 amp fuses. Right now, I cannot use the A/C and heater blower motor anymore to which I am considering wiring a bypass to the car battery.

    um, it blows because it is drawing too much current

    try unplugging the blower motor, if it doesn't blow with the blower motor unplugged, I would replace the motor

    Does this setup use a connector somewhere inline from the fuse panel to the heater?

    I know on the cars GM used a wiring plug that had terminals that were too small. The wire that drew the most juice always seems to melt the connector.
