I did a google search and concensus came up to having 347hp and 355ft/lb torque. i tried playing around with that vent actually but still no air on backside. Don't know why there is such a vent inside the console. probably previous owner placed something small in the console and fell inside the vent hence clogging the passage to the back? That's the best I could think as you have explained how the rear vent passes through the console first since there is air coming out from the console. Thanks.
