There was a site that covered this procedure, but it's no longer up. The procedure involved removing the ACC pushbutton panel and getting access to the 5 electric switchover valves that control the center nozzle flap, legroom flap, defroster nozzle flap, main air flap, and fresh air recirculating flap. There was some disabling of valves I think, but definately rerouting and replumbing of these lines to allow recirculated a/c at all times, which cools the car better in Texas summers. Anyone know how to do this?

Thanks
