Need to know what year. If I'm not mistaken the earlier models have a separate rear heater core and a/c evap, while the newer ones duct everything off the front.

The 2nd Gen has a rear heater core, so several possibilities. I assume the fan is working? If that's the case you could have a plugged rear heater core, a failed hot water valve not allowing flow to the core, or a failed mix door not allowing air to flow through the rear heater core. Maybe another thing or two I'm not thinking of.

Second Gen MDX has a separate rear heater/evaporator. It's weird that it's blowing cold air when the front is blowing hot and not the other way around, which would be an indicator of a potential problem with the blocked/non spinning fan, for example.

Could it be the rear climate controller that has gone bad? Do you have anyone with a Second gen MDX 2007-2009 to try and swap the module (it's pretty fast and simple) and see if that works?
