Update on A/C system problems

[632 Regal]

Thanks to BMA...I will have the replacement pressure switch tomorrow. And, if all goes well with DIY job then I should be enjoying A/C this weekend

FYI. The pressure switch p/n = 64 53 1 390 070 (BMA p/n = BM044273) and costs less then forty bucks.

Thanks for all of your help!

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???

Awesome man. This is one for the books. Good thing you got that expensive electrical diagnosis and compressor replacement from the repair shop, right?

If the aux fan works on low speed when A/C is on, it means that the resistor is OK.
Resistor is used only for aux fan low speed operation.
