Subject: Re: Need Help Troubleshooting Vacuum Lines for Heater Vents (was Vent Vacuum Query)


And the answer is: No. I found three problems. First the vacuum hose from the tee on the engine was not connected; next the vacuum hose at the vacuum reserve canister leaked at the pressure valve connection; last a vacuum hose underneath the dash but above the floor vent assembly was disconnected from a tee. To fix these problems I hooked up the hose at the engine tee (this is where the vacuum originates), I spliced the hoses at the canister thus bypassing it, and I hooked up the disconnected hose under the dash. Ouila! Now everything works - but what a pain to troubleshoot. Hose problems 1 and 2 were not that hard to figure out but the 3rd one took forever to find. Anyway - just thought you all might like to know. Hopefully it may help you in future. -- Allen In article <7n7jfk$jr9$1nopsam16.us.oracle.com>, apickelnopsamracle.com says... > >Hello Everyone, > >I'm trying to figure out why I'm not getting any heat to the floor or under >dash vents.
