Channeling Scot Minesinger........... my 69 was converted before I bought it. It hardly blows cold this season. Does anyone have and experience/thoughts on those all in one cans with the gauge and hookup to recharge/add to the system? Does the conversion system need frequent adding of refrigerant? I read a couple of the kits and it seems pretty simple.
You should Not need to continually add refrigerant.
I am commenting with minimal experience and a little (dangerous) knowledge. I have heard that 134a leaks more than R12 so it stands to reason that if your conversion was not a complete re-build, that adding more from time to time might be needed. My '81 Seville is now on it's third year (I think) since being converted and when started up this spring did not blow ice cold. I will have my mechanic add some before the trip to Hickory Corners for Fall Festival. (Next month, I will not have a lease payment, so I'll have some extra $$$ to do this.)
Thanks Barry, that's what I have found. All the info points to adding by those kits from time to time. It seems pretty easy.

Check the site glass on the top of the dryer/receiver. If there are bubbles the system is short of refrigerant and you should slowly add refrigerant until the site glass is fleas. It is normal for cars that aren’t driven frequently so top off the charge runs the.car and the AC atleast once a week and see how long that holds before you start looking deeper.

Fleas in the sight glass would seem to indicate a larger problem. :P
Now THAT is the last word!

Yabbut, since they're so small, they shouldn't pose a problem, unless there are an ess-load of 'em in there.

Ain’t autocorrect grand. Of coarse that was supposed to be “clearâ€

Jim,
Added 134 to my 1970 Caddy ten years ago still blows cold. You may have a leak and green dye can be injected to help find it. Usual leaks are compressor seals, original never replaced "O" rings and original hoses. Another thing is if it was not properly converted to 134, where everything had to be flushed out.
The best thing to do is drive with the top down. Ha ha, I know you want it fixed. Probably has a slow leak.
Thanks Scot. I agree, I think the conversion was done on the cheap. I'll probably just drive with the top down on the cooler days!
