1993 Park Ave: what kind of coolant??

I'm amazed how hard it is to find this basic info. Is it the "old" (134) or the new crap that I can't put in myself?
PS I assume this is the problem since it gradually got less and less cool and worked less and less, till the point where when I hit the A/C button it would just default off of that and go to the "economy" (residual air) setting.
Any help greatly appreciated.

1993 was the year of change. There may still be a readable sticker underhood to tell you or just look at the larger and smaller lines from the compressor. The service ports will either look slightly larger that a tire valve or look like the snap connectors (if you take the cap off) like for air tools which would be 134a, the other R-12.
R-12 is restricted and 134a available but PLEASE post back for info if you want to try to service your own. The info that comes with this stuff is lacking. Don't buy products with any sealers in them - just the plain stuff.
Be safe with this, hit back if you need more help, good luck,

To add to my prior post, the car could have already been converted to 134a but service of it now should be the same if that happened. FYI 134a is over the counter still in USA, stay safe,

Tom, greatly appreciate your posts. Believe it or not, just getting back to this as this is a 2d/rarely used car....till now, that is, as my primary is now unavailable. Anyway....
It has what looks like an overgrown tire valve cap on it (ie those little black screw-on covers), about the size of my thumbnail. Sounds like the old stuff, true? If so, how do I get this "restricted" stuff?
PS: if this proves extremely difficult/expensive/etc to buy, what happens if I juice it up with new stuff? It's an old car, so frankly I don't care if I mess it up long-term, but short-term, will it work and not totally screw up the system? Thx again!

That was the switch year! If your fitting look like air compressor fittings you are 134a. The car should have a label under hood so you don't have to guess unless you don't know it's history - it may have been changed over from 12 to 134. Bonne chance mon ami (Good luck friend) Tom
