    Have a 06 Deere 200c that the heater has been blowing cold all fall/winter. Have both coolant valves open and can try different settings on control panel and does no good. AC works good in summer. Any ideas ?

    Backflush the heater core. Just make sure your flushing the opposite direction of the coolant flow.

    Also, blow out the fins on the heater core, I've seen them so packed with dust/dirt they look like a brick.

    verify everything on your heater control is working. I've had issues with some of the buttons not working on the older C model machines. Maybe its not switching your vents properly and pulling outside air?

    Also check on the heater core that the valve that controls coolant flow is opening and closing.

    At 12,000 hours my 270 had a clogged core. Easy fix.

    If both heater hoses are hot, then the coolant is circulating and the air is blocked. One or both hoses not hot, then the coolant isn't circulating. That will get you pointed in the right direction.
