If you're putting oil in your air conditioning system, you should probably get the entire system replaced. A/C needs freeon/refrigerant. Do yourself a favour and get a mechanic friend or even an actual mechanic to do this for you.

There is a power distrobution box under the hood containing relays and a few heavy duty fuses.
I'd take the cover off and find the A/C relay usually depicted in the diagram inside the cover.
Start the car, turn the A/C switch on and then under hood at A/C relay give it a light tap with the handle of a screwdriver to see if compressor clutch on compressor "kicks on".
Relay can even be pulled out and put back in to make a better connection.
I'm betting the problem is that relay...or dirty contacts.
Hope this helps...
