Dodge Repair: 99 Dodge Dakota AC, hammer and screw, screw driver

Question
I am having trouble with the AC in the Dakota. This spring I re-pressurized the systems and it seemed to work for about 3 weeks slowly dying. I figured it was a slow leak so I put in the anti leak R-134. The system worked for the initial 10 minutes or so then started to blow warm air, and now the compressor does not turn on at all. I was wondering if there is a low pressure sensor in the system  or if it would be the compressor its self that is going out.

Answer
turn on the AC system  get a hammer and screw driver  hit the front of the clutch but watch out when it starts to spin it will throw your screw driver if u dont move fast. IF that did not work then u have a big leak and it  messed up the compressor or clogged up something from the stop leak crap u put in. They never work ne way.
