I installed a 140 cfm 12 vdc vent fan with a 3" duct into the dash where it split into two 2" ducts. One for the driver side and one for the passenger side. I did this just before we drove to the LCS. I tried it a couple of time and just got hot air. My foot box does not get that hot but you know how it is. Coach Mike install one in his Cobra so I had to install one in mine. The jury is still out. Mine cost about $120.
As hot as it gets in Alabama I need an aircondition.
North Alabama, is has been 90-95 for weeks.
