Ok, for all you people out there with AC low pressure switch problems, I found the solution without bypassing the switch. ( I'm referring to the switch with a probe that goes in the low pressure side, which shuts off the compressor when the pressure drops) After searching the web and find others out there with the same dilemma, I called dealerships and found 1 in the US, but it was on special order, the PN is 56005783, so on when on a hunt through the manufacturer Ranco, which let me to the manufacturers company Inven Systems, that makes them, I had to go from there to a distribution company to other vender's and found a company online called www.action-ac.com, the sell the part, here is the link to the part http://www.action-ac.com/AC-Part/32-40012.html, good luck out there with this, I hope this helps

 

Any update or info on where to find the switch?
thx

 

I am not finding it anywhere. Discontinued at any mopar site, and no other listings for it anywhere.

 

i have a1991 dodge d350 and found the copper tube broke. Do you know if there is any other alternative to maybe fixing this problem? Thx for any help.
