Greg Rider Posted December 23, 2010 Share Posted December 23, 2010 What year and model of truck? Is it the factory switch or an add on like a Truck-lite? It may be something as simple and hard to trace as a bad ground. Quote #1 on A-model registryIf I drink because of work, why can't I drink at work?

Rob Posted December 24, 2010 Share Posted December 24, 2010 Do you turn signals work normally as in left and right? I mean not using the 4 ways? If you have a problem with the turn signals also, look for a grounding problem. If the turn signals work normally and the 4 ways do not, look for a flasher being bad as most vehicles do not share the same unit.
