I installed a set of Pacesetter LTs over the weekend and now my vents inside my car dont work. No matter what setting I have it on, it will only blow out the bottom. I removed all of the vacuum lines on the drivers side of the motor that went to the EGR/AIR, could one of these have caused it? Is there any other vacuum lines I could have knocked loose? I am pretty sure it is a vacuum line.

Shoebox, thanks for the quick reply! Actually, right after I posted I did a search and found that page, and sure enough thats what it was, and now they blow great. I think it has been loose for a long time because when i would get on the highway my A/C would cut out. You are a lifesaver shoebox.
