Having an issue with my climate control. I think it was related to the vacuum/climate control canister near the front of the car in the engine compartment. The canister that came with the car had the watercock/solenoid nipple, the nipple going to the firewall, and the nipple going to the intake. The intake vacuum line was teed off at the intake manifold, going one direction to the cruise control, and one direction to the vacuum canister. With this canister I wasn't getting any doors opening or cold air to enter the cabin, only getting hot air through the defroster...
Then I went and grabbed what I could from a local salvage yard, another canister from an older model Z. This one instead of having the three lines mine had, it had an extra nipple for the climate control. I plugged this in and I could not feel vacuum from the port that goes thru the firewall just like my old canister. I got plenty of vaccuum from the cruise control nipple. So tested the vacuum by instead of attaching the firewall line to the firewall nipple I attached it to the cruise control nipple. Now whenever I hit the digital AC button I could see ventilator door open(dash is off) and a lot of cold air rushed inside. However when driving the door would close and I would get hot air upon accelleration.
So I'm kind of confused what is wrong here, I think perhaps both canisters aren't the right one for my car, that maybe the PO used a canister off a manual climate control system. Sorry for the poor explanation here, but does anyone have any insight of what to look for or what may be going on here? I have looked online, looked at the Chilton's manual and the Field Service Manual. I would think the whole problem is with this vacuum canister and not something inside the car because IF I do get vacuum the doors work, unless I accellerate.
