Please Help with A/C.
Hey,
Recently replaced intake and did the Truion rocker arm upgrade. While doing these mods must have done something that affected the A/C control. Air coming out of all of the vents. When I move the adjustment switch it does not do anything. Must have popped off a vacum line or something. It is a 98 C5.
If anyone has any ideas what it could be. Any help is appreciated.

That vacuum line runs down through the wiring harness, under the battery, and then into the cab. It drives the A/C damper doors that direct airflow to the different vents.

This is a very common complaint after doing intake work. Its likely the vacuum line that comes off the back of the intake manifold, has become disconnected (or was not reconnected)

Is it a hard plastic around 1/16"?. I found a line like that completely broken off. What I did is take a small vacumn hose and slide it over the the broken line and ran it to the back of the intake manifold. maybe it is leaking or not a tight enough seal? Does that sound like the correct line?
