1969 Chevrolet Impala
Howdy - I'm working on Vlad, my brother's 69 Impala.
"Vlad The Impala"
The turn signals stopped working. I checked the bulbs, the fuses and preemptively replaced the relay. Still nothing and then the Hazard light button broke. Since I needed to replace the Hazard light switch I ordered the turn signal switch and canceling cam (and the Horn contact parts because that decided to die too) and I replaced everything all at once. The horn and the Hazard Lights work great now, but the turn signals still don't work. They don't light up at all unless the Hazard Lights are turned on. Help me please.
Following a wiring diagram I traced wires from the turn signal relay in the under dash fuse box out to the front left corner where the fender meets the radiator support. Mounted between the fender and the tiny little coolant reservoir is a relay. Based on the wire diagram this relay is part of turn signal operation. Ok, I'm game. I'll call it part of the turn signal circuit. Following the diagram I see where it feeds wires to the front turn signals. No problem there. There is a red wire on the front right that is hot.
There is a black wire on the front left connected to a terminal marked "Bat". The other end of this black wire is hanging out not connected to anything and this wire is hot.
Where does this damn wire go? If the wire diagram is correct then this black wire should feed through a channel in the upper radiator support and across to the passenger side front turn signal. There, in approximately the equivalent location to the relay, is a wire junction that has a black wire connected to it that appears to have been run to it from out of the upper radiator support.
What in the AF is going on here?
Included are numerous pictures of the relay in question and the wire diagram I have been referring to. I know the diagram is for a Nova, but it matches the one for the Impala in the Haynes Manual. I just couldn't find an online copy for the Impala.
Help a brother, my brother, out.
