1988, S10 Blazer 4x4 with the 4.3, having trouble with the turn signals. Already tired different turn signal flashers and switches. The driver side turn signal will turn on and flash but only with the truck started and the light switch off. If I turn the lights on it'll stop flashing but stay on. Passenger side will only turn on but won't flash wether the lights are on or off and the cluster will turn my left turn light on for both sides of the switch. But if I turn my flashers on all the lights work fine. Ive changed the flashers, relays and checked for power and ground. At this point I'm at a loss. I've checked for power and ground as well and that's there. Not sure where to go next. Could my cluster be shorting out an casing this problem?
