2nd row has no heat from vents? What can I do?

Hello, the second row turns to heat but doesn't produce heat, correct? In this case, a temperature blend door motor may be of concern in the second row. Hands on testing will be required to determine if this is the case. There's really no difference between the second row and first row as far as heat being present, it's more about the distribution of that heat.
