My front left turn signal is shorted to the parking light somehow, all other lights are functioning normally. I verified the short is NOT in the bulb or socket with a volt meter. Looking at diagrams of the cpu and signal switch i cant really see anywhere these two wires could be shorted together, any ideas?
Car is a 1987 Turbo 2

 

Well now i feel like I'm suddenly stupid, the right turn signal is reading shorted as well but works fine. in fact all 3 pins on both harness connectors read shorted together with a volt meter.
The left front turn signal flashes the low part of the bulb with the parking lights off, but with the parking lights on it interrupts the low (park) bulb. It also starts flashing faster when the parking lights are turned on.

 

Figured it out, ground in the socket was bad.
​​Lesson learned: don't probe your light sockets with a volt meter, they all read shorted for some reason.
