Does a 2001 have a recyc door vent - or is it 100% OA?

Hello,

With all my heating issues - I do have a question that I can't find on the net.

- Does a 2001 4.3L have a recyc door vent that just recycles air across the heater core from the inside of the Van instead of 100% outsdie air. I know on my really old car 1982, there is a lever that selects 100% outside air or 100% recyc air from the car.

Thanks

You can try the MAX A/C position with the heat control turned all the way to the red hot , that position recirculates the interior cabin air to reach maximum cooling when the A/C is in use by continuing to cool the already cooled cabin interior air , it may do the same for the heated air as well

I just looked at my 97 manual and can't find a chart that shows which position the fresh/recirc door is in for the different modes.
Rule of themb is:
AC: Fresh
Max AC: Recirc
Heat: Fresh
Defrost: Fresh (Compressor will be running to dehumidify cabin)

I'll keep lookin' :D
