Anyone know of a company that makes a new 6 volt dash fan? There are plenty of 12 volt versions -trucker fans-, but the only 6 volt versions I've seen are the old, open-rubber bladed versions or the metal ones in cages. I don't want pay the big $ that they want and then find out that the rubber is brittle, or the motor needs rewinding. Driving around the San Joaquin Valley in the summer without wind-wing vents makes the inside of the wagon rather toasty. The cowl vent helps, but I need a more active solution!
