Hello there cats and kittens just an update on my AC Center vent situation. I purchased an aftermarket vent from Summit Racing. It probably would have worked but did not have the Aesthetics I was looking for. So I came up with an idea that is working quite well. I took some foam that I got at a craft store. $0.98 and it comes in a sheet like letter size paper. I cut it into little slivers and forced them into the vent at appropriate angles creating corridors so the air to flow through and painted them black. Which I'm not happy about but I can swap them out for silver ones I'm thinking. Anyway took it for a test drive this morning and it was beautiful.
Just to take this one step further —-if I may
I truly do not think the systems design is the issue at all having owned my 64 convert when new
The convertible would be less efficient at containing the cold air than a hard top by design
I would attribute the problem to some worn comfort control parts ( compressor ? )— a change from R-12 to 134-R freon— the fan motors output speed—and the condition of the window rubber seals in your own car
Not sure how many of the above you may have already addressed that might help
I surely understand the very hot conditions you have being in southern FL is adding to your situation
Be COOL my friend —— (even if the CDV could be a bit cooler inside at times )
The AC fan SB blowing — really big time —when on high —at start up in a hot cabin and fan speed slowly tapper off as you get to your set temp on the dial
Could your fans —MaxRPM that it reaches be some of the possible problem ?
I would like to know myself what the max RPMs are for the blower fan that is working to the correct spec on high
Do jump in ( anyone ) if you know that rpm number is !
That fan has a circular unit very much like the Sturn of a river boat that may be rusted or damaged
The FINS on that disc is the part that does the actual air movement thru all the ducting under the dash
Might be a good idea to get a look at the max rpm fan speed on high you are getting and the condition of the fins on the air moving disc attached to the blower motor that does the actual air movement
You did cover all the basis I see
Do you have the STV after market valve installed for the 134-r freon you are now using ?
That’s it -out of ideas - Over and Out !
Sixteen years is a long time on any ACs systems parts regarding wear and performance
You must have had to do some maintenance thru the years to keep the. System performing correctly
Yes, as you know these cars require constant maintenance and replacement of parts.
