:iagree: I have the same Problem after 10 - 15 minutes of driving mine starts to get heat back there and after 30 - 45 minutes you can cook the people in the back seats out.

I don't think mine is really a problem it's just normal operation. The bulletin vball61 posted is more for the person that wants there rear heat to work more efficiently.
