So yer saying that u put a valve on yer heater input hose and shut off the hot water circulation so the hot water doesnt cancel out the cold ac air? Seriously? I've noticed that many of the Dakota/Durangos I've looked at have had ac cooling issues. When u turn the heat on or off, doesnt that stop the hot water flow as well? I live in Title Town Tampa and never ever use the heater, since we dont have a winter season. Just summer and fall seasons. And hurricane season!

For most of the older ones (and I think a lot of the newer ones, but don't KNOW so)? Nope; it just moved a flapper around to redirect the air; the heater core was every last bit as hot.

Cars from the 60's for sure, lots of them had a manual valve in a heater core hose. I think the manufacturers stopped that because it led to a lot of heater core failures from clogging. Keeping the coolant flowing in the core keeps sediment from settling in there.
