I have a 2005 SRT and when I use the key fob to lock (or unlock) the car the only lock that works is the driver side. The hatch, the gas door and passenger door remain open. Also the switch on the console does the same thing. I pulled the vacuum pump of the central locking system from the back of the car. My question is does anyone know how to test it? The three little plastic nipples (attached to yellow lines are all supposed to emit air when locking correct?? I took the housing that holds the 2 lines off and hit the lock function on the key fob. Only one of the nipples emits air. I don't think I have a vacuum leak anywhere ...I really think it's a bad pump, but before I shell out $400 for a new pump I would like to be able to test the one in my car. I've checked fuse #9 in the fuse box...it's good. Any help bench testing this unit would be appreciated. vr, Lee
