The left one is slightly cooler if working properly. If no heat, flush the entire system, pull the heater core hoses and flush that thing both ways, (I soaked the core in CLR for 35 minutes, not recommended by some mechanics) then flush it like crazy. Put in a new thermostat, and you should have heat. That should cover it, hopefully one of the first things is the problem. Good luck.
Actually taking out the heater core is my very very very last option, cause that things a b**ch. But you said remove the blend door? like remove it completely and go without one? How does that work? And I'm going to try the hoses later and see if they are both hot, I hope they are cause then I know the core isn't clogged atleast.
