The most likely cause would be either the turn signal stock, the circuit between the turn signal stock and the body processor module, or the body processor module itself. I would start by grounding the pink/green wire at the turn signal stock connector, if they now work, then you have a faulty turn signal stock/switch. With that being said, the body processor module has F.E.T. Transistors that will open when a short is detected in a circuit, so another easy test would be to cut the two green with pink wires at the body processor module, disconnect the battery for three minutes, reconnect the battery and check for voltage at the green/pink wires coming out of the processor. If you now have 12 volts, or a flashing test light, connect one circuit at a time to eliminate front or rear. This will narrow things down for you.
