I have a 93 SSE with about 75K miles, all stock.

I've had no air conditioning the last couple of years. Heater worked okay in the winter, but for the last few months the AUTO function wouldn't work.

I just had the refrigerant changed over, THEN read about FREEZE 12. Oh well.

Today I got back into this forum and checked for help. I checked for trouble codes and found a low freon code. I also got my AUTO function back! Still no cold air, but there'* now hope.

I'm going to go back to the guy who did the changeover and see what he can do.

Maybe we can get a bit more 134 in the system and get it blowing cold again. It'* over 100 tomorrow, and I don't want to broil to and from work again this week.

Hope someone out there can help.

Stay safe, and may God bless.

With the low freon code, it sounds as if you have a large leak in the system and simply lost all the 134 already. I hope this isn't the case :?\

I can relate to your auto-econ problem....I'm low on refrigerant, and in the evenings when the outside temperature is cooler, the system detects low pressure and reverts to econ, but during hot days the refrigerant pressure is higher and Auto will work.

It'* easy to do yourself. You can buy everything you need at Wal-Mart for really cheap. I would say that you have a leak. When the mechanic changed your car to 134, did he replace the accumulator and add an orifice tube? He SHOULD have. The most common place for a leak is right on the back of the compressor. There are two metal lines bolted onto the back of the compressor. Take them off and there are two metal washers with a rubber coating on them. You can get replacements at an A/C shop for less than $5. I would say that 9 out of 10 A/C leaks are these two seals. Replace them, and charge the system with 134. But you might also have an A/C shop find the leak. They have leak detecting machines. At a good reputable shop, they'll charge around $30 to $40. Good luck! Matt

Thanks for the quick replies, folks.

I was kinda tired when I wrote that last night, and I left off some pertinent information.

I was trying to find out how to tell whether the A/C compressor is running. It'* a little hard to see, but is the front part of the compressor supposed to be visibly turning, or does it appear to be stationary if it'* working properly?

I'm not that much of a gearhead that I've learned all this over the years, but I am just brave (and stupid, maybe--must be the Irish in me) to tear into stuff if I have the right help.

From what I've seen, you guys ARE the right help.

Thanks again.
