HVAC Vacuum Valve Clip-need the one for the Power Control side

[Norman Silverman]

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

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."

[Norman Silverman]

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.

[Norman Silverman]

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.

[Norman Silverman]

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.
