Ok, so my AC, when turned on, just pumps air out of the bottom vents by the floor. Nothing coming out of the vents that face the driver (the important ones). Not even hot air. Just no air at all. Anyone have any ideas about what it could be? Thanks

check your vacuum line near the back of the intake going to the hvac controls. may have popped of.

back of the intake manifold? thats all good. I just recently did an LS6 intake swap and made sure, but this problem has been happening even before i did tha swap.

Check the "T" valve over by the PCM.

YES! That always cracks. It's like a $6 part. Easy to change.

It's called the vacuum check valve.

The line that says "To mode selector on dashboard" where does the line plug into, the firewall? My vents dont change with the switch and that line is loose, cant find its connector.
