*

you have two size of ac heat one huge one tiny the smaller line is the high next the press switch because that the short side offered to be at the AC drier periodically at or next to the compressor either way the low press will constantly be ~ above the bigger of the two lines.I could be more specific but you to be not particular on the engine you have which could adjust the exact location.

So why room you trying to find the low push switch?It have to be ~ above the Drier as I mentioned earlier. Here is a web page I uncovered online the points all the switch areas for you, a simple google search uncovered it.https://ricksfreeautorepairadvice.com/2 ... Locations/
I have done plenty of "simple google searches" and got the same an outcome you did...its ~ above the drier. Yet there is no one top top the drier of this GMC. Ns don"t understand if the Silverado has actually a various A/C system however as have the right to be checked out from this snapshot there is no press switch or a ar for one top top the drier. It has actually the short side port however that"s it. Im guessing that is down close to the compressor.

You were appropriate this to be a ache to uncover online, from what I view it perhaps compressor an installed The just indication the this at every was ~ above the PartsGeek website that reflects the 5.3 does have a compressor an installed low pressure switch. Which means the mechanism would have to be recovered so you can change out the switch. Gm shows it as number 5 on a diagram yet provides a generic picture of a low pressure switch.

No problem, so why room you wanting to locate it? do you have a full charge and the compressor clutch is gaining no power?
I have a 2011 silverado, very same truck very same engine. As far as I can tell, this hvac mechanism only has actually ONE pressure sensor and also its located down close to the compressor on the high pressure line. Lock stopped putting the low push on the drier part years before apparently. I have actually a complete wiring diagram because that this truck and also NO where on it does it present a second pressure sensor various other than the one under by the compressor on the high push line.
Sorry for second post, ns am having actually an worry with mine whereby I"m not getting any kind of power in ~ the compressor uneven I remove the relay and put in a paperclip jumper. I"m thinking probably I have actually an worry either v the manage module or the fuse block itself. I have a full charge of freon and have got rid of everything down stream that the fuse block together the problem. If friend would favor I can upload a copy that the wiring chart if that will assist you. I have diagrams because that both the automatic and also manual hvac systems.

I to be not having actually an dispute of what your truck or the OPs truck has actually for factory equipment, If girlfriend went out and looked at her 2011 truck which is not a 2010 exact same as the OPs and also your van does not have a cycling move sticking out of the compressor it just does not have it. ( I definitely do not know much more about your truck 보다 you do particularly if you went out and also looked over the compressor ) however to suggest or hints the OP must not look at his 2010 compressor over based on a partial wiring diagram the belongs to a 2011 seems kinda presumptuous.I remember back in the day before 2000 the GM started adding a cycling switch and also doing away with the switch at the accumulator which drove me nuts earlier then and aggravated me since it take it what to be a an easy job that unscrewing a sensor and also screwing a new one in place to the following level v recovering refrigerant instead of the accumulator and also orifice pipe evacuation and recharge every for a stupid switch. ( save in mind i did no mind the extra the supervisory board )As much as her truck not gaining power unless you operation a jumper seems to me you may want to examine your compressor and also or truck end a little far better as well. AC systems require both high side and also low next protection how GM has actually done this i cannot tell girlfriend on your 2011 or the OPs 2010 indigenous what I have seen low side is safeguarded with a short side to ride bicycle switch.Let me clear this up i am not saying ns am right and also you room wrong ns am simply posting what i have discovered without either van in former of me ns am entirely clueless. Which pipeline to the details I to be able to uncover online.Yours reflects up top top the GM site https://www.gmpartsdirect.com/oem-parts ...

My cursed truck has an growth valve rather of a orifice tube.The ac accumulator is no where insight ( turns out come be placed to the condenser like they used to back in the job ) would certainly be cool if they began using a sight glass as they come in handy when recharging or topping off a device that to be low.
