Problem fixed, thanks to all those who helped! Installation took about 15 minutes -- piece of cake. The amount of refrigerant lost is dependant on how quickly one can unscrew the switch -- not much leaked out. The wires out of the back of the switch slow the removal and installation process.
I was disappointed to see that my auxiliary fan is still not functioning. Not exactly sure why I was able to get it to operate when I jumped the pressure switch, but with the new switch installed it still does not work. Low speed with the A/C on, not sure about high speed. I'll attempt to jump the temp switch located on the side of the radiator and see if that kick starts the fan. If not, then I plan to replace the resistor. Sound right???
