my 96 XLT i am sure has a booster fan, and it works fine. My problem is i just picked up a 2006 limited and it has no flow to the back seat. It doesn't have a switch for a fan or raido controls for that mater in the rear of the console. It such a nice truck i can't belive they left these minor conviences out of such a nice truck. The raido controls ar a minor dissapointment but the flow of added air to the back seat, cold or hot is not understadable. The lack of a switch on the console i thought might be due to the electronic A/C, somthing like the computer knows when it need to blow more air to the rear as the front also has auto fan setting. The possibly the fan or resistor going bad would explain the low flow. What I am trying to find out is, on the newer models when Ford offered aux. rear as an option the decided to drop the booster fan to boost sales of their optional equipment. My parts guy at ford even though I do purchase what I have to through OEM seems to have less and less time for me on the phone since i have bought my 2006. I am just wanting to find out before I pull the console out if their is a fan to be found.
