Heat randomly stopped working
I'm new to the Duramax. I recently bought an LB7 and everything worked great! I've made a few little changes and I had no complaints until last night. My heat decided to start blowing out cold air. I checked all my hoses and they were all warm after a little drive, engine temp gauge is still working which tells me it couldn't be the thermostat, I pulled an HVAC fuse to see what happened and still no change. Can someone help me please? It's snowing outside and I'm not in the mood to have no heat.
