Re: 64 Malibu SS dash harness problems
The power coming from the black/ltblue wire goes to the dimmer switch which switches power to the high or low beams. If power is coming out at the switch, check at the floor dimmer switch to see if power is making it there. Then check to see that power is coming out of te dimmer switch terminals. One will light the low beams and the other the high beans headlights only. The red wire only supplies power to the headlights through a circuit breaker that is internal to the switch.
The other switch sounds toasted if you have power coming in the red and not coming out of lt blue terminals on the switch.
You need the power to come into the black orange wire to run your tail and park lights. This power comes through a fuse at the fuse box. Check the tail light fuse for power at both lugs of the fuse. Flip the fuse box over and look at the back if you see no power. You might find a poor connection at the terminals on back of the fuse box. If you still see no power, follow the wire (I think it's red or orange in 64 ) see if you can find a break or bad connection.
The purple wire goes to park lamps and brown to taillights. With the wiring as it came from the factory, first pull out of h/l switch turns on tail and park lamps. Full pull out of h/l switch turns on headlights and taillights, but parking lights are not lit. There is an easy mod to keep the park lights on with the headlights on. It's listed in stickies above. We can get to that if you wish once we get the lights working properly.
