alright, ive recently put a new compressor and all on my ac system, vacuumed it out and then refilled it with 134. it still doesnt blow cold, the guys at Autozone said i need to replace my pressure switch. Does any one know where this is at, and how to replace it? Thanks alot in advance guys

 

the pressure switch is located on the refrigerant line going to the evaporator box inside the car. ...follow the refrigerant lines going to inside the car...you will see a 'pod' perpendicular to the pipe with 2 wires attached. **note** consult your manual and/or professional help if you are unsure about the a/c system's integrity; improper charging can cause ruptures in the system and damage to the new compressor.
