Do you know if the system is empty? You can check by pressing the pin inside the connection kinda like letting air out of a tire. If it doesn't let any pressure off it is empty.

No, It is still cold. It only gets cold when you are driving it. It does not get as cold when you are sitting there. Almost room temp. It needs alittle more. If it was empty, I would just put a vaccum on it and retrofit it with r134a. But why replace something if it is not broke right.

I will wait until it no longer gives cold air I guess.

Even if you did have it vaccumed you can buy a conversion kit for about $40 that will come with everything you need. It would still be cheaper than having the R12 system serviced. Last I saw one can of R12 was running over $60.

Sounds good maybe it will stay cool for the rest of the summer or even longer.

R134 was first used in the Bonnevilles in 94, but I'd like ACG or Fuddy to confirm that.

1994 was the first year of R-134a.

Your system sounds like it could be a little low, or your condenser could be clogged. Have a reputable A/C shop check it out. It may need 12oz or so of R-12.

I've got a couple of cans I'll sell you cheap... Oh, I'm sorry officer !

In all seriousness, there is another option to consider. There is a product I use in all my old vehicles called Freeze12. It's $8/can, and uses R12 gauges and fittings, but you will need a vampire tap (they sell it cheap) as the cans have a unique fitting. It really works well - it doesn't get as cold, but cools-off the car more quickly if that makes sense. Much better than a typical R134 car now, and infinitely colder than you'll get with a dump and fill 134 conversion to your bville. You can add it right to R12, but I would whole-heartedly rec. pumping your system down to make sure it's tight, then use Freeze12. It's available at Advance and I'm sure other places. Here's the link to their site - it has all the info you need, plus a link to the cert. test if you want to get your 609 cert. and be able to buy R12, too. I have no contact to them or anything! I've just used their stuff and have been VERY satisifed.

e-mail me if you want to pursue this and I'll give you details of my experiences.

I have a few cans of r-12 I could make a killing.. to bad its iligal

How much do you want for them?
