Undo the serpentine belt.
Disconnect 2 electrical connections
Remove 2 small bolts from backside of compressor.
Remove single bolt securing A/C hoses from compressor(WARNING, system is under pressure. Better to vent system before doing this step). Either vac it out, or just let it vent out. If you vent it, your violating EPA laws. Unless it leaked out on its own.
Remove 2 large bolts from front side of compressor.
Wiggle it out.
Voila.
Installation is opposite of removal.
Please see vehicle service manual for proper oil and refridgerant recharge quanities.
For more information or pictures of this task, please feel free to ask a member of this forum.

Default Is there a valve

I added the right amount of freon/oil to my system but it'* still not cooling...the compressor is kicking on and off and blowing reg. air...

Is there a valve that might be clogged?

Did you tip the can upside down to fill it with freon, or was it rightside up to pressurize the system?
