W123 Vacuum Leak - jkeam - 06-25-2009 Hi, I'm having a problem diagnosing a vacuum leak. The door locks always work when I'm driving. After shutting off the engine, I have to rush out of the car to be able to lock all doors with the key turn. If I wait over 20 seconds after shutting off the engine, the key turn won't lock the remaining 3 doors. Anyone have an idea what is causing this or how to fix? Thanks, Jim RE: W123 Vacuum Leak - SurfRodder - 06-26-2009 obviously a slow air leak... try isolating each vacuum system and then once you figger out what system is causing the problem, isolate each 'circuit' until you find the culprit... that being said, it might just be better to replace all the hose and be done with it... RE: W123 Vacuum Leak - ForcedInduction - 06-26-2009 Use this diagram. The two 4-way connectors are under the front carpets and plastic covers. At those two junctions you will be able to test all but two actuators individually and isolate the leaking one(s) without needlessly taking off any door panels. |
