I need identification help from someone that has a 1969 Cadillac with factory air conditioning.
Request 1:
I have one vacuum line on my 1969 Cadillac, that I have no idea where it is supposed to go to. I need a couple of pictures of the firewall, under the hood of the car, along with a description of where this one vacuum hose goes to.
Request 2:
At the front of the engine, there is a thermal vacuum switch. If possible, I need to know what vacuum hoses are connected where on the switch, and where do they go to. I know that one vacuum line goes to the vacuum connection at the bottom of the carburetor, but I don't know to which terminal on the switch the other end of this hose attaches. Another goes to the distributor, but where does it go on the switch? The third one goes to the heater / air conditioner control, but which is the terminal that it goes onto? I have no idea what the 4th one is for. I had thought that 3 might be identified by the letters on the switch, however, this is one of those times you need to be certain. I am thinking that the M stands for manifold, and the D for distributor, C for carburetor, and that would leave the last one for the heater / air conditioner. Problem with this thinking, is that there are a number of vacuum lines on the carburetor, and there is no vacuum take off on the manifold for 1969.
In picture 1, you can see the thermal vacuum switch is located between the distributor and the power steering pump.
In picture 2, you can see the mystery vacuum line sticking up. This line has a yellow tracer paint line on it for identification purposes from the factory. Unfortunately, the factory vacuum diagrams are not available in the service manual.
Picture 3, is a overall shot of the firewall so you will know where to look. If you can't determine where any of these lines go, possibly multiple close up pictures will allow me to follow it like a detective with a magnifying glass. You can post up to 8 pictures to each reply, and the more detail the better. I have been struggling with trying to get my heater / air conditioner working, and without locating where this vacuum hose goes, all is lost.
Thanks Paul
