I can verify with my 2010 acura tsx 2.4, the 3 pin connector, you make the jump between 1 & 2. After I did that, the compressor ran without cycling on and off. It was just ON. It allowed me to add the appropriate amount of freon. Now i need a new ac pressure switch 🤑 thank you so much RB the mechanic. You helped me big time with these diagrams.
U have to vacuum the system to add and use machine
Just a word of caution to all you guys, anything more then two wires has a 5 volt reference wire going back to the computer...PLEASE identify this 5 volt wire before you attempt any bypass. I have seen it go wrong. The motor will stall and the computer will be fried and suddenly you could be out a grand and maybe even a tow to a dealer.
Yuppp
Yeah, I just tried this before reading this 🤭🧐🤔 When I jump and get the fans going the ac console freezes up …
@@ANGIEB52 so it could be ur pressure switch u still need to test other things
😊🙏 thank you!!! I was just about to test a 3-wire setup... No thanks! Headed to the store to get a multimeter and replace the switch....
@@danielsmith9130 yupp good idea!!
I have a 2006 jeep liberty. I tried recharging the system, but it wont take refrigerant. If i jump the ac clutch relay the compressor kicks on but it wont kick on when i try to jump the low pressure switch. The low pressure switch is new. I replaced the compressor because it burned up. I put the gauges on and the ac system and it has no leaks, it holds a vacuum. I haven’t changed to orfice tube or the receiver drier. What could cause the low pressure switch to not be jumped?
thank you again!
Welcome
2 is the 5 volts from the computer, and 1 is the signal, so you jump from 1 to 2, then you have a direct 5 volts straight to the computer, and telling the computer that, the pressure is so high, and it may not run the compressor. It has to be a certain return signal in order to get the compressor running. That is my guess
Thanks!!
Good video
Thank you
thank you very much
Wecome
So if the juming doesn't work what could it be
Did u check to see pressure in the system or power to ac compressor
Thanks for the video,. Pls with 2006 Infiniti QX56 do i need to evaquate refrigerant to replace the presure switch or does it has a valve?
Not sure if it has valve I would recover the Freon from systym just to be on the safe side
My old car has just a simple two-wire switch screwed to the top of the receiver-drier. Is that the high-pressure liquid side ?
Do I just pull out the connector and jump the two pins ?
I find this switch a nuisance and unnecessary expense. My previous car never had such a switch on the receiver-drier.
Think so some cars have 2 switches what car is that year make model?

I am in Malaysia. It is a 1996 Proton Saga, with the Mitsubishi 4G13, 1,300 cc engine.
The airconditioner compressor is a Sankyo (Sanden) SD-505, with R12 Freon gas.
Does the refrigerant have to be evacuated on Odyssey 2005 to replace ac pressure switch or does it have a valve?
I don’t think it has a valve
@@RBTheMechanic thank you for the reply. It did not and the system had to be evacuated. Thank you for the information.
Tried jumping my ac with switch unplugged and used a paper clip ac still doesn’t come on what is it
U had 2 prom switch?
@@RBTheMechanic It has 3. When you jump the relay itself the clutch wont click either.
Is this switch by any means responsible for turning on fan when turning the ac on...
The whole system of ac works with each other
07 Honda Odyssey - relay is ok - i jumped the relay & i get power in to the compressor however with the relay in place nothing happens , any ideas? faulty pressure switch?
Tnx!
Did u check to see if ur systym had as Freon pressure?
@@RBTheMechanic
@the end was a faulty compressor
Changed relay switch fir ac clutch still not wieking
Wire diagram to swutch
I tried to jumped the switch but the compressor still not engaging
When u just it try checking power on compressor connecting it gets power and it dosent engage then it’s bad compressor
@@RBTheMechanic i tried jumping the relay, the compressor works fine. It can just be the switch?
@@nanieberoin4902 well did u check Freon pressure
@@RBTheMechanic Yes sir,
Hey Mac
Please help me with my car 2 pin ac pressure switch.
How I can check it with multimeter.
I just don't know what position should switch will be either closed or open ,when car ac is on and when car Ac is of.
I am Checking it with Continuity .
When my car ac is off ,the switch shows no continuity means switch is open.
And as soon as I turn my ac on switch shows continuity means switch is closed .
It it how it works .
Is my Presurre switch working Fine?
Use om meter check om s. Also I can jump the connector see if systym come on
Wow you talked to much just go to the point
OOOK
Lol so what happens when your ac wont show on in the car after you do this incorrectly
This is only for test
It doesn't work with three pin
Nope 3 pin is diffrent
😂🎉
