ok this is the skinny, I turn on the air to feet and dash in position 1 or 2 and there is no air coming out regardless of whether cabin air or a/c is on.

If I move the air flow to a position higher than 2 air comes on at the level expected. Level 3 air or level 4 air, as though nothing is wrong. But if I move to level 2 or 1 it goes dormant for air flow. All the lights stay the same.

Around this same time I noticed that if cabin air is off and I'm in some position other than MAX A/C the exhaust smell comes in. I think that is unrelated though.

I took the air panel and traded it with a buddy of similar year and the problem was still there. I tested my switch with his truck and it worked fine. So its not my switches, its something down stream. I'm stumped as I no longer have alldata

 

Check the resistor pack behind the glove box.

 

by the way the answer on your signature must be Darrel Issa. How do you know if a politician is lying? His lips are moving

 

can you specify where behind the glove box?

 

found it

 

The question is rhetorical, but we'll leave the politics in OT..

Glad you found it, they're a relatively common failure item.

 

that fixed it, u da man

 

Wow! Thats great. Any chance of a picture of the area wear the resistor pack behind the glove box is? Thanks and good luck...
