Hello, new here. I have a 2000 chevy tahoe z71 with the 350ci engine. Cant find online any of the vacuum line diagrams. While underway, the recirculation door for the hvac will just periodically open and close depending on throttle setting. I have recently added a ford vacuum pump and 1970s vac canister to help out, but this has not fixed anything yet. The one the I isolated was on the driver's side, ran across the top of the block and then ducks into the firewall near the a/c dryer. Are there any other lines that run this system?
Thanks
