Behind the glove box you will see a vacuum pot with a rod running vertically down below it. That rod moves the blend door.
Try selecting different venting options and see if rod moves.

Thanks, guys. I guess I have to chase this dodwn, but I'm going to start at the lines I put in with the Ranger heater valve mod... seems to be the most likely places where my problem might exist. I know that the vacuum pump is kicking on because that's always my signal to take off whenever I start the engine cold.

Sounds like you have more than one leak or a bad pump. Unplug the line going to the soleniod right beside the pump and do the same and see what happens. Might try both at the same time and see what happens.

Tried that too the only line that makes it stop is the one running from the reservoir to the pump. It would turn back on because of a bad seal around my finger, lol.

I disconnected the short line off the vacuum pump running to the reservoir on the pump side and pluged it with my finger and it stopped. I went down further and no luck, i will try tomorrow when there is more light outside, thanks

Yes my 4WD does work, not all of the time some times i have to play with the switch and it only goes in for sure every time when the hubs are locked and not on auto. I was hoping to resolve this problem tonight but i forgot my wife has to work and she took the truck, she thinks its hers, and sticks me with a turd of a car (Caliber).
