Re: Rear tail light turn signals
Good plan Kevin, I still think it sounds very simular to my issue I was having, so I still think it's a ground issue. I had lights too, parking, brake ect., but was doing strange things, one side worked, one side didn't, flashers would cause differant results as would turn and brake.
Drove me nuts, I think new sockets and scuffing/cleaning were sockets ground to housing is your culprit.
Mine was also a brand new rear harness, American Auto wire, and I still needed to slightlly bend all tabs out a bit to get a rear good ground. You can have a s slight ground, thus lighting up the park lights, but when applying brakes or flashers, draw more volts causing the weak ground to cause funky issues. These cars are a lot like the old Christmas tree lights as the electrical system is a loop from battery, back to battery with each system or harness a strand of Christmas lights, one "bulb" not working right will cause funky things.
