I'm trying to add refrigerant and don't know where? Another noob question!
Thanks for the help.

Check up under the passenger-side ignition coil/jump start terminal, where your arm will be assured of being burned as you attach/remove the charging line...

The recharge can doesn't fit...woohoo! Yes it's R-134a.

There's a really good case for charging the system with the engine COLD and NOT RUNNING. Biggest is that it helps you avoid the burned hands and arms around that upper hose. Next is that it's much faster to push liquid into a non-running system. Hook up the hoses, and charge LIQUID by holding the can valve-down, and adding a little heat to the can. Depending on system ambient temp, this could be as easy as holding it in your hands to warm it up. If system ambient is over 90º or so, you may want to use some warm (no greater than 120º) water in a pan or bucket. That will push liquid from the can through the hose, and that liquid will flash to vapor after it's in the car system. Wait a bit before you start the car and turn on the AC, so there's no chance that there's a slug of liquid going into the compressor suction.

Another question. I have no idea if/when the A/C last worked, do I need a conversion kit or something from R12 to 134a?
Thanks.
Thanks.

I don't want to be an a$$, but it sounds like you do not have much experience working with A/C systems. I would suggest that you either take it to someone who does, or spend a good amount of time studying the intricacies of refrigerant systems. You could easily ruin your system, or at worst, you could seriously injure yourself.

Well really, it is not all that hard (other than getting to the ports) to add some fridge to the system. And since it does not work now, the worst case is it won't work later either...
I don't think ANY of my systems have been converted to R-134... admittedly it was MUCH easier in the R12 days!

Yeah, if I could find some R12!
