Default A/C Issue

I modded the car for the last 6 months, nothing "major" but now the A/C doesn't blow out of the top vents. It'll only blows cold air out of the top/defroster vent, and the bottom vents.

Any ideas?

Really? The servos that switch the gate that diverts vent flow is controlled by engine vacuum. KISS that is why it is still used

yeah if you did an ls6 intake or removed the AIR system there's probably a vacuum leak from one of the lines in the back somewhere

you didnt hook up the vacuum ine to the port all the way at back of intake.

you will find the line and fitting between the ECU and engine area
along firewall.

find it and plug it back in.

I would be the one to throw it away... yup. I got a new line, and now the fishing begins to find the line from the back of the firewall!
