anyone know about airconditioning for these things?

When i got the car it had the airconditioning stuff on it. The mexican who sold it to me didn't even know it had it on there! So i put a recharge kit in it with the sealant and it pumped out ice cold air for about a week. now its warm again, but the compressor and everything still work and it still has the coolant in it, i've checked. so if anyone knows any tricks to it, let me know please---

when you say it still has the coolant in it, do you mean it is still the exact same amount that you installed with the recharge kit? run the car with the a/c on and look for the lines freezing up before the evaperator coil. ie, check under the hood and see if they are frosty. If you are getting low on freon, sometimes it will expand and cool before it gets to the air exchange coil. Your description sounds just like a slow leak... No suprise since it has not had oil running through it for (possibly years) to keep the seals and o-rings from drying out. You may end up having to change all o-rings and the compressor seals. If you end up doing that, you may want to consider swapping to 134a freon to reduce the costs down the road...

I recharged it with 134a. It got ice cold for a week. From what I can tell none of the lines are frosted up. Any other ideas?

need to make sure the little doors in the console are changing to the correct position when you select a/c. I have not studied the system on the fiero so I am not sure about this. I just noticed that mine make plenty of noise when they move around... other than that, use a 134a gauge set and see if your compressor is compressing. only other thing, your orifice tube may be clogged if there is any contaminates in your system. I live in AZ, plenty hot here now. I just received my fiero about a three weeks ago. its blowing hot air. after I get the new fuel injecters and see if the drive train is going to work... then i will convert to 134a. i'll report on the progress... sorry i can't be of more help.

sorry about the wait. I did convert my a/c to 134a and so far ok results. I removed my compressor and it was a HR-6 which i am told is a good replacement for the not so good DA-6. I disconnected all of the fittings that had o-rings and replaced them. Most of them were the captured fitting style which is a thicker o-ring than normal. A couple were the normal style. I saw two places that looked like they had been leaking, the connection at the left forward part of the engine bay and the condenser fittings. With all of the fittings apart I forced some flushing fluid through the lines and components with 120psi air pressure. I also installed a new accumulator and VOV orifice. The compressor label said that it used 8oz of oil and 40oz of R-12 so I used 8oz of PAG oil and after putting it all back together, charged the system with approx 32oz of 134a. It may have been a slight overcharge but nothing has failed just yet... Oh, I forgot to mention that I reset the low pressure switch from 25psi to 20psi. I now get 40 degree air out of the outlets and a new problem... the car slowly starts to over heat at highway speed. No problem just driving around town. Outside air in Phoenix has been around 105 to 110 the last couple of weeks.

so much for my a/c.

Do you know if your car has a V-5 compressor? or a DA-6. I read somewhere that the V-5 is a variable stroke compressor and I wonder if that may be causing problems and still appear to be working? I also heard that the DA-6 was a bad design and you should not use it with 134a...

ok, life is better. I fiddled with the low pressure switch some more and ended up setting it at about 15psi. seems low but the air is now coming out at around 32-34 degrees and the system does not cycle as much. I also just had the radiator rodded out and that seems to have fixed the overheat problem. it was a low mileage radiator but had been sitting for almost two years. the green coolant turned to rust orange by the time I got the car. I guess the chemical reactions were going strong and plugging the radiator... additional note, the radiator was a two core and OEM radiators for the Fiero are one core.
