When I was troubleshooting my A/C system, I discovered that the pressure switch is located on the receiver/dryer "can" in the right-side wheelwell. If you jump the two prongs in the connector on the wiring harness, it should fool the compressor into coming on. However, I would be inclined to take my car elsewhere, since many A/C systems have a low-pressure cutoff, and most A/C technicians should know that (and how to deal with it).
