1996 Ranger XLT 4x4 4.0l -- not able to adjust heat.

When the fan is on I continually get hot air from the vents. Turning the temperature adjustment knob to cool (counter clockwise) does not change the temperature. If I listen carefully when I turn the temperature adjustment knob I can sometimes hear a slight grinding sound....not fan related, more like a baffle moving due to vacuum. Difficult to describe. Anyway, I took off the glove box to take a quick look for anything obvious.

So my question to all you gurus -- is the air blending (hot/cold) baffle in the heating plenum (the big black plastic assembly behind the glovebox)? Is there a way to access this? The book indicates I need to remove the entire interment panel to get access. Maybe, pull the and inspect that way. Ideas?

I found my EVTM manual. I suspect the 'blend door actuator' (not cable controled) as this looks to control the temperature door in the plenum. Anybody, have experience with this?

Often times a pen falls down the defroster and jams it up...

Only a few bolts to get the dash loose...and flop it out where you can get a good gawk at it.

Assuming the vacuum lines are hooked up
