Hi.
Update:
I removed both 7 nipple vacuum valves and called my buddy who owns a machine shop. Tomorrow we'll re-surface the valve faces and then I'll reinstall them. HOWEVER, the one that comes out easily and comes apart with no rivet is on the Power module side. It installs on one side with a small bolt, and on the other it is held on by a clip, WHICH IS MISSING ON MY CAR. I am going to assume it is the same clip that is used on the Control Module side. Anybody got one? Happy to pay for it.
Thanks
Norm

Thanks. Guess I better read more attentively.
As noted in my reply yesterday "it turns counter clockwise looking down from the motor end toward the cage."
Quick question: Which way is the blower cage supposed to be turning (from the vantage point of looking DOWN on it), Clockwise or Counter Clockwise?
Thanks.
VERY good suggestion.
About the "old man" thing: Don't know how old you are but you will see that as you age physically, you will still be at a certain mental set-point between your ears. For me, that's 17 and coincides with when I first drove cars like this. So, it may be an inconvenience but after having way over 100 old cars over the years I'm not about to stop now. And, with a great group like this to support me, I'll figure this out. Stay tuned, and keep the suggestions coming.
Anders: I cannot fault your logic.
Unfortunately, most of the old time workshops are gone; owners retired or died and the younger folks don't want to/don't know how to work on stuff like this. There's probably a place that will do it, but I have not found it yet. I prefer to do it myself because I like to learn about it first hand, however as I've aged I now have certain limitations on what I can accomplish.
Will be getting to this again in the next few days and will keep posting. Meanwhile, thanks for the input.
Two things will be a deal breaker: 1) If I have to remove the hood hinge (too inexperienced to know how to properly brace the hood), and 2) The AC line is directly below the blower motor and is just long enough to to to the expansion valve, meaning it may not have enough give to get it aside to let the motor drop out. Because the refrigeration system is working properly, sports a rebuilt compressor and does not seem to leak I am VERY reluctant to evacuate the system and move the hose. I will think on this and hopefully figure something out. THANK YOU!
I used the term "halves" to be consistent with the wording in the shop manual under Blower Inlet Assembly removal where it references removing the duct (see below). There are just s series of 1/4" screws at bottom of motor holding it to case. I would just take a light and look both blower motor screw, or the duct halves bolts and nuts. Either will take a bit of effort but not that bad.
How difficult is it to remove part of that duct. Removing the motor looks like a bigger job, and I have reason to believe it is good and installed correctly. I think I have a blockage.
Yes, that's the duct I have been referring to. And, yes the blower blows strongly. When you referred to it as "halved" I thought I could pull of a section of it to either directly inspect or put my camera down to see if it is blocked, which is what i expect. With the fenders and hood off, it looks easy but with the car intact it is a bit tricky. I am going to try to remove more bolts. I took the top 4 off that duct, which allowed it to open and I did feel a breeze. If I can get more of it open or off entirely, I can inspect and vacuum it out if necessary.
There is only one metal duct that feeds from the blower motor and air inlet over to the evaporator. See the duct circled in yellow below with green arrow pointing to air flow direction: You stated in your last reply "I think the primary feed duct under the hood is blocked." I assume this is what you are referring to as it is the feed duct to the evaporator and into the air box once it goes through the evaporator. As far as removal, it will probably be easy just to remove the blower motor, pull and bench test. Regardless if you put 12 volts to the connector at bottom of motor it should be pushing a very strong flow of air in the direction of the green arrows in pictures below.

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?

Hey everyone, has anybody done a Vintage Air AC/Heat setup in their car? I want to bypass the old vacuum setup and go with a Vintage Air Gen 2 model. Before I get started, does anyone have any experience with this? (Which model to go with, do’s and dont’s, etc.) It looks pretty involved. Any and all info/pics would be greatly appreciated. Thanks!

Who rebuilds original AC accumulator dryers for 1964 Cadillac? I have been on Classic auto air in Tampa FL wait list for over a year , There is one on Old air products web site that looks very similar to the original # 21-4214A but states it fits 1962 Gm cars, The one recommended for a 1964 Cadillac is half the length 21-4215A What is everyone using ? I would prefer to be as original as possible. Thanks

My son, unbeknownst to me, had all three of the horns on our 1963 Eldorado completely restored. We had recently added the Eldorado trumpet horn to the two standard horns and the sound was not very good... we had heard good ones so we knew something was not right... but there was not much we could do to get better sound from the 3 horns.
There is a restoration service called The Horn Works who my son…
