I just purchased a 1997 Ford F150 XLT 4.6L. I noticed that the A/C and Heat are only coming through the defrost. After a little research found out were to start looking. Needless to say I found out it was worse than I first thought. I was able to locate two of the lines which are the white and red that connect to the vacuum reservoir which is locate behind the battery against the wheel well. I have no idea where any of the other ones go. Any help is appreciated.

Here are what is in my Ford service manual. It sounds like the shift actuator lines for the 4x4.

The last picture is from another SM and it covers the 4x4 vacuums, which show the red line. Hope these help/

Thanks for the response. After some therotical guessing I found it. I had to pull the passenger fender well and tucked up inside was another resivior which is where the larger black, smaller black, white and tan lines connecter. The resivoir behind the battery is where the red, small black and white vacuum lines connected. Now the panel switch works correctly and took care of my ERG sensor error.
