I noticed this evening that my 1994 Chevrolet Lumina (same basic car as a Buick Regal) uses the R-134A refrigerant. I thought that 1995 was the first year for this. I know cars can be changed, but mine is original, I think, as there is a factory tag under the hood and there is no other sticker stating it was changed over. My A/C is NOT working, so I am glad it is the R-134A, as I know it is MUCH, MUCH cheaper than the R-12. It says the car holds 2 lbs., and I think it is about $4 per can. <BR>Does anyone know when R-134a refrigerant was first used in a GM car?

R134a is used in almost all GM in 1994. All GM had it in 1995. A very few GM were set up for R134a in 1993, (seals, elastomer hoses, etc.) but were charged with R12 at the factory.

Last year, in response to the need to repair the weak A/C in my '91 LeSabre, it was converted to a non freon system. If I'm not mistaken, by law, (IL only?) dealers are prohibitted from recharging Freon based systems now. They put in a conversion kit & fixed the source of the leak and the A/C ran fine for a July trip to KC in my BLACK LeSabre 4dr (can you say HOT!?) The repair parts & labor were way more than the conversion kit ($140? vs $700 for the leak repair) BTW, the car averaged around 32 - 33 hwy MPG at 70 MPH.
