Title: Vacume
Post by: DCustom on December 08, 2013, 12:06:22 am

OK, I have a 84 with a/c. There is a vacume hose (black with white stripe) coming from the control panel that is not hooked up to anything nor is it plugged off. Can someone help me with this

There should be a black round vacuum canister that it should be hooked up to.  I can take a picture of it tomorrow and post it if someone hasn't already done it.

Thanks zieg. Are you talking about the canister on the right kick panel?

No, it is under the hood

It may also be on the drivers side but that black looking ball is what that hose needs to be connected to and the ball needs manifold vacuum

this one was under the dash...after giving up last night I went back out there fresh this morning and there is a canister behind the heater box that you cant see that had a available place so I put it there....I wish I had played with the a/c heater controls a little before I tore everything down to see what was and was not working....but I do thank you for the info....Im starting under the hood next week
