1997 E150 temperature controls
Hey ya'll-I'm a new member and looking to see if anybody knows how the blend air door is controlled=whether by vacuum or cable.It seems that if I use the heater-then the a/c doesn't seem to work so well.I'm thinking maybe the door doesn't fully close whe I go back to a/c.Is there any way to access the blend-air door to troubleshoot the problem.If it's cable-actuated it probably isn't sticking but maybe it is if it's vacuum operated.The temp control is a radial ****.Any thoughts?

The blend door is driven by an electric motor that in turn is controlled by the temperature control on your dashboard. One vacuum servo re-directs air flow from defrost, vents and floor but it doesn't affect the blend door at all.

I would take this Forum's advice over Ford's advice any day. Those Ford engineers never had to live with these vans like we owners do.

Oh heck yes on those factory manuals Henry---VERY misleading sometimes! Mine is on a CD-ROM and when looking for remove/replace the heater core I honestly thought I'd selected the wrong section---"remove steering column........." WTH?? Even when I re-read it I was still just lost!
My saving grace is knowing more than a few very qualified mechanics who ply that trade daily and know the easy quick ways to make repairs. While I wouldn't have removed my dashboard to repair the heater its still good to have someone in the biz. BTW they laugh every time I mention something from my manual!
These heaters seem daunting at first but now after having done one I wouldn't hesitate to do it again because its just not that difficult. Try one-------you'll see!
