I noticed the other day while driving that there are some vents, atleast they look like vents on both the driver and passenger sides of the center console under the dash. and atleast on the driver side I'm getting alot of excess heat with out the A/C on, it's almost like the heater is on the floor setting and on full blast. So it's pretty freakin hot... Is this normal? is it just engine or exhaust heat? I have a 2010 2wd titan with banks monster exhaust. Thanks!
