The temperature of the water going to the heater core is at engine temperature [200+degrees] hot enough to cause a severe burn!!! Found out why the right side rear heat is not as good as the left side rear heat the transition duct from the heater to the floor duct is missing so the hot air just ends up in the console area. This explains the lack of heat in the back on the right side. It also explains console area gets very hot. For you folks with work vans if the heater for the back heat is not correctly blocked, then the heat will dump in the console area when the heat setting is to the floor. You might check and see if you feel air blowing out around the edges of the console. That is how I found the location of the missing duct.
Now I have to see what the dealer is going to do.
I think that when the duct is correctly installed the rear heat in the TC will be fine, Just in time for winter in Crazy cold Vermont!!
