My rear vents are not that stong either. Also, the temperature adjustment control does not work as well as the front controls.

If you think you have an issue, you can always check your vent connection. If is possible that the vent ducts might not be properly seated. (This can happen if you have removed and reinstalled your console for trim replacement, IPOD install, etc.) If you remove the inside tray located under the armrest, you should be able to access/see where the ducts connect.

In all honesty, I am a little dissappointed in the design of, and with how the rear vents work. The air flow is not that strong, and the temperature controls are weak. Also, if you close the rear vents, air pressure quickly builds up and escapes generating some noise emanating from within the console.
