Turns out I do not have power at the back up light bulb or the flasher bulb. Not sure why I said that in the earlier post. Let me give a little background here. I've been dealing with this issue for 2 years. I did a 5 speed swap last year, I had these symptoms previous to the swap. Sometimes everything will work as it should, and other times everything is dead.
The back up light switch is new (and the correct one) and the wires are clean and tight to the connection. I replaced the turn signal switch with a new one from blunt. The hazard switch is new and has the correct pin out for my car. I have 2 stock and working flasher relays, and I also have the electronic relay that people have been using (the symptoms are the same regardless of what relay is in use). I took the ignition switch out and cleaned it, no change. All grounds for the circuit are spotless and tight. All wires leading to fuse #6 are intact, spotless, and tight. With the ignition on I have 11.8 V at the fuse. I took out the rear bulb trays cleaned and sanded the bulb contacts. bulbs are new and fit fairly tight in the sockets.
What's really got me confused is when I turn on the hazard lights, all signals flash like they are supposed to. Where does the turn signal switch get it's power? As I understand it, the TS switch completes the circuit when engaged, so does the power come from the ignition switch?
The only places this circuit comes together is the bulb trays and the fuse according to the wiring diagram.
