Since your car is pre 1995, and likely hasn't been switched over to r12, you will have to find a mechanic to charge it up. You need a license to buy freon now. If it has been switched , you can just get a refill kit at Walmart of most other parts or hardware stores. If it has been changed over, it should have a sticker under the hood somewhere.

    I'm sorry. I said R12. I should have said R134a.

If you are able to but the correct refridgerant (r12 or r110 I think) you need a pair of manifold gaiges, some leak test and a vacuum pump. There is a high and low side fitting in the lines from the compressor to the evaporator. The gauges are red and blue. Follow the instructions in a service manual to draw down, leak test and re-charge the system. It's not usually a do it yourself proposition unless you are familiar with refridgeration principals.

First, you can't legally get Freon. It's banned. Amazingly it was banned just after the Dupont patent expired.
You should be able to use 134-A as a suitable replacement. Just purchase the conversion kit that is available at most auto parts retailers.

95 Cadillac seville added 2 cans of freon and unhooked battery cable, still on cold air and car states freon low. How many cans does it need if empty?


2 lbs of freon is all you need if empty, replace your low pressure switches, sit on a thin a/c line running on top of your fire wall from one end to the other, you will need to recover the freon before you can replace these two sensor's. These sensor's are bad that's why it reads on your dash low freon.
