[12Ounce]

As soon as my '99 Winny arrived, I disconnected the "mode" actuator ... as I never really understood the reason for it, and it always caused constant irritation to folks in the back if the driver made temperature adjustments. The temp blend door was left working.

As far as the circuit is concerned, its made more complicated by the fact that there are aux controls for the driver and aux controls for the rear passengers. About six pages, or more, in the circuit diagram book. If you want to send me a postal address to my private mail, I will paper copy these pages and send to you "snail mail". Or you can try searching Ford Publication "FCS-12255-99".

Of course, your model may be significantly different from mine. Have you tried visiting a Ford dealership and copying their work book? I find there is usually a person who will help a DIY ... for a coin or two, perhaps.
