I have several problems with my vaccum (I think).
1. None of the doors lock centrally. The trunk lock also will not maintain open position. I have to unlock it each time. 2. Engine does not shut off immediately. I have repaired the one known crack in the vaccum lines, but don't know how to test which lines are good and which are not; nor do I even know if the vaccum works at all. Any ideas, techniques on how to test the pump? The lines? How about repair? Am I better just having all locks manual and forgetting central locking? Thanks, ------------------ 81 300D 250K+ (odo doesn't work!) Want another one. |

Josh,
This subject has been covered a number of times. Suggest you do a search on vacuum leaks in this forum. Posts have covered testing and repair. Good luck. Hope it turns out to be an easy one. ------------------ Ted 1979 240D 160,000 miles |

Get yourself one of the cheap plastic hand vacuum pumps and start at the lines through the firewall next to the oil filter. By connecting the pump and pumping a vacuum, each circuit should hold the vacuum for awhile after pumping it. If the pump holds the same vacuum for 10 seconds or so, your problem is not in that circuit. I think the leak you are leaking for will be significant.

Where is a good place to get a cheap vac-pump for testing?

I think AutoZone carries the MityVac pump and brake system bleeder.
