QuestionQUESTION: On the power brake booster there is a vacuum connection coming out of the front. It has three connections, 2 of them are connected the third is not. I cannot find where this connection goes to. I have looked at the haynes manual and also at the vacuum guide under the hood. I cannot make heads or tails of it. Could you please help me so that I can get the care smogged. Thank you very much.
ANSWER: Hi Bobby,
You didn't tell me the year, make, model, engine so I have to guess. One should come from the intake manifold (the biggest diameter, one should go to the cruise control module, and one should go the heater/ac control switch in the cabin if the this is a pre-95 of most of the models but not all. But be specific and we can go from there.

QUESTION: The year is 93 Chrysler lebaron 3.0 liter engine 6 cyl. sedan. I have a picture if there is a place to upload it. If not it is the one that comes directly off of the power booster vacuum coupling. two go to the sides. one comes off of the front. that is the one that I am unsure about. Never mind about the image I found the place to upload it.

Hi Bobby,
Did you get the vacuum line hooked up OK? If you would like to tell me there is a "Thank/rate the expert" button below which if you click will take you to page where you can "comment".
May I also ask a favor? On that same page you will see the question "Would you like to nominate this expert to be 'volunteer of the month"? If you will click on "Yes" that would be appreciated. I am competing for that recognition which is based on nominations from questioners like yourself. Achieving it will increase awareness of the Chrysler repair category.

Hi Bobby,
That looks like a small diameter hose connection and I suspect that it is indeed the one that comes from/to the vacuum operated air distribution control switch in the cabin. If you look at the firewall about at the mid-line of the car, and about the same elevation as the heater/ac control panel in the cabin, you will find a thin vacuum line coming right through the firewall and that is the one that needs to be connected to your open vacuum nipple. On the vacuum diagram it is the arrow "to climate control".
