With proper retrofit... Yes
In 1915, Alfred Mellowes designed an electric refrigeration unit that differed from other refrigerators because it was self-contained; the compressor was in the bottom of the cabinet.

You always have it work but if something goes wrong and it does not work trash the wonder card and try again and it will work!:)

If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
First of all, you don't use R12. Rather, R134 which has the oil included.
If your vehicle is a 1994 or older is contains R12. 1995-96 It man contain R12 or R134. After 1996 it will contain R134. It is listed on a label near the compressor dryer. Engine size means nothing.
R134a.
Should be R134
R12 134A pre 1996 is r12, after is r134
You would have to replace the orifice tube, accumulator or receiver-drier (which one you have depends on what type of AC system you have), as well as remove all of the R12 refrigerant, and you'd have to replace the compressor oil with PAG.
R134a
r 134
If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.
This is the transition year. It can be R12 or R134. It is listed on the unit. The fact that R12 is no longer being produced makes it extremely expensive. Convert it to R134.
