A/C assistance !!
I've had my GTA For about 6 yrs now and my A/C just quit blowing cold. My question is how do I tell if its been converted to R-134a or if its the original R-12 coolant?

If there is no sticker, and you have screw on quick connects for the low side and high side ports, You could have either R12 or R134a.
If the high and low side ports are still the threaded connections, then it is still R12.
Hopefully you have a sticker. If not, it would be a good time to convert.
