The rear upper unit is A/C ONLY, No heat. The rear heat comes from the rear console between the front seats. It is blown through tubes from the front under the front consloe. There is no rear heat blower per say, though you can direct the rear heat for mid, and lower console outlets, and of course off. Again, The rear upper is A/C ONLY.
And just to add. My A/C has never really blown cold, and my heat is NEVER hot! I'm thinking the heater core also. You repaced it yourself jeffs22? How was that?
