Re: A/C charging issue resolved.

After researching the IMON archives, I've come to the conclusion that I'm going to have to pull my vent motors and see how the gears look inside. Particularly the center vent motor. One archive post suggest unknowledgeable techs inserting temp probes into center vents as a probable cause for breakag...

Re: A/C charging issue resolved.

You should be made aware that even with an improved design vent flap, you'll have to periodicaly visually check each vent's flap actual position for the selected EATC positions. I observed that the OE flaps seldom stopped in "clean" full open (perfectly horizontal). That may have been a r...

Re: A/C charging issue resolved.

Ed, I take a slow, and systematic approach to these things. I also take a minimal risk approach. My first step was to address my driver's side vent which was jammed. After addressing this I might have left it with that as my other vent doors were functional, but upon close examination, not optimal. ...

Re: A/C charging issue resolved.

When I said - "My vent doors and motors are working fine. My whole A/C system is working as it should." that was before I pulled the vent deflectors off and had a look! Up to that point I could hear the doors operating, so I assumed they were good. However your other recommendations (sans ...

Re: A/C charging issue resolved.

OK, so I have the driver's and passenger's side vent doors installed and they work exquisitely. Easy motion, nice seal, "edge on" throttle blade when open. Much better than original design, and I believe the passenger side was previously misregistered in the full open position. The "p...

Re: A/C charging issue resolved.

It's not a question of the foam gasket binding. My original plastic door was binding along the axis of the pivots, against the side walls of the passage...to the point where the door froze (i.e., the motor could not over come the resistance). Very certain the passageway has shrunk over time along th...

Re: A/C charging issue resolved.

I think I figured out why these vent doors jam up, the vent doors distort, and the motor gears fail (and sometimes the EATC driver chips blow) I was trying to figure out why my new vent door was getting squeezed side to side. I made it the same external dimensions as the original vent door. I am qui...

Re: A/C charging issue resolved.

Well, Ed - I'm not tearing things apart and breaking stuff. I'm making it all work as original, hopefully better than original. This is the nature of the restoration hobby. As opposed to "To heck with those dang doors, rip them the heck outta there!" and... "I'll stuff my old socks in...

Re: A/C charging issue resolved.

[Are you keeping track of how many hours you've invested in this?] YMMV It's a hobby. The design time is small. The initial layout was done in a morning. Subsequent tweaks take only moments. Printing a vent door takes about two hours. Progress is slow because I'm doing other things. But hopefully i...

Yep, noticed the prices on ebay. You got a good deal. I hope they fit well into the Scorpio.

Re: A/C charging issue resolved.

The overall layout of the seal mimics the original seal, which was foam. The difference is that it is very thin polyurethane. Overall, my vent door is much more aerodynamic than the original vent door, mostly because it is thinner and smoother. On the next version I made it "designed for assemb...

Re: A/C charging issue resolved.

The good news is that my driver's side door motor works. The bad news is I broke my new vent door while trying to install it. Onward to the next revision. I'll add extra support. Definitely need to print it on the FDM printer out of ABS so that it will be tough, but flexible. I think I will shrink t...

Re: A/C charging issue resolved.

Well...wish me luck. First prototype. I'll try fitting it tomorrow. The body on this one was printed on the UV resin printer. I've already revised to go to a two piece body that will allow it to be more easily printed on the conventional FDM printer. The polyurethane seal was printed on the FDM prin...

Re: A/C charging issue resolved.

Disagree. It comes down to improving the effectiveness of the condenser. https://griffiths.com/ac-system-help-introduction/r134a-vs-r12/ "Pound for pound R134a is a more efficient refrigerant than R12, however it runs at higher pressures in some aspects and therefore requires more effective con...
