I have an 05 Saturn Ion that has a malfunctioning body control module. The circuitry to flash the front signal lights has been damaged (common problem). I could replace the body control module however it is very expensive (upwards of $600) and also requires reprogramming by a GM dealer (additional expense). I am trying to come up with a low cost work around with some simple circuitry to bypass the BCM. My problem is however, this vehicle uses switching from a single wire connected to three switches with three different resistance(s) to ground. I have a basic understanding of electronics and got as far as I could but I am having difficulty working out how to get the switches to turn on the relays. Anyone have knowledge of transistor or IC circuitry that can complete this schematic?
