    Either I'm blind or they hid the heater valve. Anybody know where it is on the DD15? I gotta get more heat into the cab!

    Well, the actual valve should be under the hood on the passenger side near the firewall. Are you talking about the heater controls? Make sure you turn on the bunk heat too or you'll catch a draft!

    They are blend air, no heater control valve. Unless there was one installed aftermarket

    Engine temps between 150 and 180. Outside temps ranging from +10 to -20. Bunk blows plenty hot, cab blows semi cool. I'm thinking the electronic control took a crap.

    Got it figured out. The electronic control on the dash went kaput. According to the shop here in Columbus, you got to replace the whole unit.

    Yeah, I said the same thing. Doesn't give me allot of confidence, lol. But so far, these Evo's have a good track record and other then this hiccup, I'm liking mine so far.

    That is why I ordered up the Arctic Insulation package on my 2013 FL Columbia glider. Even down to -20F actual, I have yet to turn on the hot water to the sleeper. The cab heater alone does a great job of keeping things warm, on that 70" mid roof sleeper.
