Thanks for the post. I have a 95 2-wheel drive and my vacuum ball is mounted to the hood on the driver's side near the firewall. Out of ball is a hose then a splitter, one of the hoses connected to the splitter broke and I can't find the rest of the hose. My A/C blower won't blow throught the vents (it only blows through defrost and floor. I know it is because of this vacuum hose but I can't find where it is. It must go from the splitter below the vacuum ball to the blower door control but I can't find it. Does anybody know where the hose comes through the firewall to the controls? For now, I put a screw into the hose to plug the vacuum until I can find where it connects to so I can have A/C blowing through the vents straight out at me. Thanks.
