Hey all. 02 3500 Cummins, heated seats both stopped working at the same time. Switches don’t blink and don’t light up, so I’m assuming the power loss I’d before the switches. Changed the relay, so I know that’s good. Been a while since I tried to figure it out but I’m 90% sure there is power to the relay. Anyone know of anything between the relay and the switches that could be the problem? Can’t find a wiring diagram of this ANYWHERE!
