Ok, I had a chance to look at the gray vacuum line under the battery. It looks fine all the way from the engine past the firewall and into the cab. No kinks, no cracks or holes.

To recap..
1) My cabin air always seemed to be warmer than the outside air,
2) even in 50 degree weather with the dials turned their coldest setting, the cabin air would always get to about 10 degrees warmer than the outside.

Fixes...
1) I thought it was the duo valves but they seamed fine.
2) I next tried the climate control mod suspecting it was a bad controls but that didn't help either.
3) I then moved to the blend door. Bingo! Its stuck in the closed position. That would explain why it's always warmer in the car since its in recirculate mode.
4) the gray vacuum tube seems to be in working order.

I've removed the cowl below the wind shield and turned off the REST button and pushed the blend door open. I then turned on the REST button, blend door closes as it should. I turned off the REST button and blend door stayed closed. I'm assuming it's not the vacuum because I believe the vacuum is what is need to close the door. My next move it to research the flap actuator under the glove box and get back to you all.
