1996 S320 V6 178K
I just purchase a 1996 S320, I noticed that when I turn on the defrost (and when I turn on the heat via climate control) I get hot air comming out the front dash windshield vent, however, I get cold air comming out the center consal (air blowing to the rear passengers). It there a switch to turn off the air conditioning to the back. I know about the vent which can be closed, however, I do not want my air conditioning running while I have heat comming through the defrost. Please advise.
