Mine doesnt work anymore maybe I could put in some freon where in the engine bay could I do this??

 

Before you go duming in R-12 at $30/pouind, you shoudl diagnose the problem.

Exactly what is/isn't the AC compressor doing? Does the electric fan start when you turn on the AC? Does the interior blower operate? Does the compressor cycle on/off?

Give a little more information, and we'll get you some answers.

 

You can't even buy R-12 if you wanted to. You have to be licensed - and rich.

Turn on the AC and check you AC clutch on the compressor. Does it turn on and off? If so, how long is the period between the time in turns on, and the next time it turns on? If it's fairly quick, less than 20 seconds or so, you need a recharge.
If the compressor clutch doesn't kick in, disconnect the switch at the side accumulator/drier - that tower looking thingy near the passenger firewall in the engine bay. Jump the connector with a paper clip or whatever. Then check the clutch for cycling. If it starts working - replace the high pressure cycling switch. If that doesn't work, you have some other electrical issue. It's a start
