Turned on the two petcock's on the engine, on the thermostat housing and on top of engine. Still no heat. What am I missing or is there more that I need to do. Ran all day with no heat, was only about 35, but tomorrow is supposed to not get out of 20's.
Most likely atc module is out, have been a issue, don't remember if there under seat like a tractor, would look at parts breakdown, if its under seat, disconnect wiring harness on r/h armrest, tilt steering wheel all the way forward, remove 4 bolts mounting seat and lean seat ahead, not a lot of room, I pinch off hoses so you don't have much of a coolant leak, Scott.
Combine has been running about 170. Did as Scott said,un-plugged harness and un bolted seat, and set it aside. Nothing under there. It sits on a solid mount. Lifted the plastic tub out of buddy seat, found some electrical stuff but nothing like I was expecting.
