the information stickers under the hood tell you, but if they're missing look at the service ports. R12 has smaller ones. they are located on the a/c lines. unscrew the caps...if there are threads on the outside of the service port it's R12, and if your ports look like air compressor couplings you have R134. both styles have valves in the center, but the R12 sticks out more and resembles a tire valve.
None - a 1995 model year car uses R134a refrigerant, not R12.
Any car newer than 1994 uses R134a. Pre 1994 uses R12. I believe the Trailblazer uses 1.8 lbs of R134a
You do not as R134a is what is approved for that car. If you could find R12 it would cost you near $100.00 a pound.
No you don't have to change the A/C Compressor.
The simple way is to remove the R12 and install R134A. by a kit with that will have a hose, R134A with oil. The new oil may plug your leaks. or go to Mexico and cross the border and buy R12 in 12 oz cans The border guards may take your R12 cans when you come into USA. or Drive your car into Mexico and have them fill your system with R12.
You can't. You have to be Section 608 certified and licensed to buy CFC12 (R12) in any quantity. Your best bet is to either convert it to R134a or R414b.
R12 was banned in 1995. Any vehicle from 1994 back will have R12. Any vehicle from 1996 to today will have R134, R134a, etc. A 1995 may have R12 or R134. Any car that has been retrofitted, even if it is older then 1994 may not have R12. If it was retrofitted it should have a label stating this.
Your car should use R134a. The manufacturers switched in the early 90's. The easy way to tell is have a look at the sticker under your hood. Every car I've looked at has a sticker that says some basic emissions data, engine size, and the type of refrigerant used. The other way to tell is to look at the two charge ports. You'll find them on the silver coolant lines, under large plastic plugs that look like tire valve caps. R134a systems will have a quick disconnect fitting (a ridge, not a thread). R12 will have threaded fittings for the hose. If you have a car that uses R12, it should be converted to R134a. The process isn't very hard, and the parts are available at most auto parts stores, if you have a vacuum pump and recovery unit. A R12 to R134a conversion kit comes with fitting converters, a flush kit (you can NOT mix R12 and R134a. Bad things happen to your equipment), and the recharge freon and oil.
It came from the factory with R12. Due to the extremely high cost of R12, I would suggest you convert it to R134a. Kits are available at most auto parts stores.
Plenty!!! Freon (R12) is very expensive and is no longer in production. I suggest you have the system converted to R134a. The shop can recover the R12 and pay you for it. Make sure the leak is repaired before charging the system.Plenty!!! Freon (R12) is very expensive and is no longer in production. I suggest you have the system converted to R134a.

Freon is the trade name for R12. Your car contains R134 or R134a which is not Freon.
The only freon available is R134a. Your car most like came with R12. That means it will have to have the system evacuated at a shop, and then be converted to the R134a. Look at the fittings where the freon is to be introduced to the system....if they are screw on, then your car needs to be changed over to the newer refrigerant....if they are quick connects, you simply need to add R134a.
