i started the truck and now it works on recerculation and the face setting but anything that has to go to the feet automatically goes to defrost and when i start the truck it goes to defrost nomatter what setting it is on

 

You still fightin this one.

 

well the ac still doesnt work but i can get it to recerculate and everytime i turn my truck off then on again it defalts back to defrost

 

I know you said you checked the lines and didn't find any problems, but this really sounds like a vacuum problem.

 

well whats the best way to track a vacuum leak

 

Any progress?
