Yes. If you do The mod that you quoted here it will run The compressor continuously and freeze up your evaporator
The low pressure cutoff switch is only to protect the compressor in the case that most or all the freon (and oil) leaked out.
Thanks, I need to figure out how to put it back to stock. I purchase the switch
, but not sure where the previous owner hid the center wire that's not used in this mod. A pic would be nice.
Lots of good info in this thread. I have run into the same problem in my 93 W250. Erratic temperature cycling switch. Part #56005783 is no longer available, and I would rather not bypass the switch. I was wondering if Jim Lane or someone else might know if this switch would work. It "looks" just like mine except the connector, which I could splice on, and fits earlier Dodge cars... It is the only 3-wire unit I can find.
Okay, I have a 1990 W150. The ac system was leaking everywhere! I had all hoses replaced and all components besides the in cab evap. Charged up the system and the new clutch would not engage. I checked relays, I checked everything. Last thing I checked was the probe. I searched everywhere and finally found that Dodge made a similar probe for the caravan, 93-...96? I’ll attach a photo. I purchased it, cut the connectors from the old probe to the wire connectors. I switched the connector ends and it works!! Paid $34 after tax, and it works great!! I live in Phoenix AZ where it is truly HOT AS HELL!!! Just in time for the heat wave! Part number is included in photo. I am not advertising for O’reilly. I’m pretty sure you can order this anywhere! Good luck!! This worked like a charm!!

That's good to know. I ended up finding a used switch at Pick-N-Pull at my it only blows 49 at the vent. I'm going to take it in soon to see if it's low on refrigerant. How did you wire the new connector?
Blue definitely grabs your eyes for attention, it has a dazzling effect,
Like the police car behind you with his light bar strobing.
Hey I know this has nothing to do with this, but for some odd reasons my a/c is more colder in the am like early and also at night time day when its daylight out side I changed all my hoses, dryer and etc
That is just a function of outside temp. AC works on a temperature differential. It will be colder in winter too because the outside air temp is cooler and warmer in the dead heat of summer because outside air temp is hotter. The trick is to get the AC cool ENOUGH to keep you comfortable when it is hot outside.
Reducing the humidity (which is what an A/C does) also increases comfort...Keeping the recirc door closed also helps because you're not drawing in moist outside air, then cooling it......Ben

Yeah I covered it with a sound proof matt over it, it sucks because I live in Florida and its really hot rn, funny this is that I went with 2 summers without ac, idk how i went thru that ahah
