My 92 300CE has several electrical issues that I think are related. First my left tailight and park lights stopped working. After several months my headlights and flashers started to blink everytime I open my door, at times will driving and when I turn the car off. It seems that the alarm system is envolved because after approx. 105 seconds after getting out and locking the door the blinking stops. And also now my sunroof tilts open without me doing it sometime during that period. Are there any suggetions on the cause or causes and corrective action I can take.

In changing the serpentine belt I pulled at a line and broke the non-return valve in the middle of the main brake booster vacuum line. My car won't stop now and it's slightly important to do so because I have to get this car inspected for a state safety inspection. I'm thinking they won't look too kindly on a car that doesn't stop ;)

From the schematics, this is the brown plastic line that gets the vacuum when the key is shut off -- so everything adds up. I'm trying to find a quick fix as I wait on parts.

#1: I haven't been able to find just the valve, I think the line has to be replaced entirely?

#2: Is this as simple as unscrewing and reconnecting from the pump to the booster? Since there isn't fluid/anything else to deal with I wanted to make sure I don't neglect anything.
