I'll start at the beginning, my battery cable broke one night i had to hooks it on the battery to get the car back started so i could make it home, the cable runs to the blower relay. I noticed my heat stop worker along with the rear blower motor (for three defrost) i stated checking fuses and noticed none was blown i then directed my attention to fusible links went behind the dash and everywhere well i came up empty. I them ran a hot wire to the blowet motor and it kick on.. I replaced the relay nothing changed i checked for power and as far as i can tell I my power stops at the resistor so I'm currently trying to find one.. I have a 1968 Oldsmobile Delta 88 with the 455 rocket and air conditioning.. If any kne could help it would be greatly appericated...

 

I would love to help you but I can't find a wiring diagram for your car. I don't believe it's the same as a Cutlass.
