I don't think you can just put the 134A stuff into a Freon system w/o the conversion kit. I am not entirely sure of what the conversion kit entails though so look into it.

R134a and R12 are not compatable. It's been a couple years since we covered this in school so I don't remember exactly why, but I remember that they aren't compatable.

You probably have a leak. And don't you need to put an accurate amount of freon into the system, not just hook up a few bottles and let 'er rip? I went to an A/C seminar, and said those little bottles are probably the worst thing ever.

^^ They told us the same thing in school about those bottles, and yes, you have to put in a specific ammount. Also, plan on putting in compressor oil that is compatible with the R134a, the R12 compressor oil is different.

You should not mix R12 and R134A
R12 is also a lubricant.
When I work on R134a systems I have to add Pag oil to the systems because R134a has no lubrication properties.
At the very least, I would recover what you have in the system, put a vacuum on the system to remove all the moisture, then maybe you can try adding R134a and pag oil.
Ive never worked on my 1g eclipses a/c since I removed a while ago before I knew anything about A/C, but on any cars A/C systems, there is a high and low pressure switch, one for when the high side pressure is at a peak, the front radiator fan kicks on to cool the condensor, thus lowering the high side pressure, the low pressure switch is to kill power to the a/c compressor clutch in order to save the compressor from lack of lubrication.
I wanted to share that last paragraph with you because these switches are set up on your car for R12 and not R134a. High and Low side pressures will be differant. It may or may not work.
I actually work on medium/heavy duty truck A/C :)

I know there are a few people who have converted their 1g to 134a but I guess it would be a good idea to vacuum the R12 out so they can recycle it and resell it and then mix oil with the 134a and I should be fine. I am going to talk to my mechanic friend about a hose with a guage. When they vacuum the system can they check pressure?
So anyone have any suggestions on where to get the r12 sucked out at?

Or just use Freeze 12.

Alright. Instead of starting up another thread I'm just gonna steal this one since it's no longer in use ;)
Since the weather is getting so hot outside and the leather seats and untinted windows just add more heat inside my car .... and my back!, I thought I'd get the AC in my car working again. It worked really well when I bought the car so Im thinking it's just low on R12 (I have a '93 Tsi).
My question - is the conversion kit a DIY kind of job? I've never messed with AC ever in my life, so I've no clue. I just read that the 'cold' line is under the intake manifold by the condensor (woohoo, fun fun!). Since it's just new adapter plugs going on, it doesnt sound very hard and confusing. Now, anyone know of a good place where I can get my R12 taken out and replaced with R134? Or just have the R12 taken out and I'll add the R134 myself cause it doesnt seem hard. Plus, I'd rather have a machine check for leaks at the same time it takes out the R12 before I go on a waste a couple cans of R134.
Im hoping to do this within the next week or so. Thanks guys!

Most chain shops offer free or cheap A/C inspections. Check out Firestone, Tires Plus, etc. for current offers/deals/coupons.
