I will try it later this evening. 
But was wondering is the pig tail coming of the drier the temperature sensor or pressure sensor?  Is there a low and high pressure sensor on the drier?  Which one is the low pressure sensor?

 I think Brian mentioned that it is the lower one. The other one is a valve I think. Just take the wires off and connect then together. Then start the car and turn on the AC. If the compressor comes on then the low pressure switch is bad, or it is good but you do not have enough pressure in the system.
